Power Folding Mirrors - Using the Mirror Switch

Power Folding Mirrors - Auto Retract Feature

The JDM and some EDM versions of the CR-Z receive power folding door mirrors as a standard feature, while the USDM CR-Zs do not. Fortunately, this feature can be added to USDM CR-Zs by swapping a few parts in the door mirror along with the mirror switch and a little bit of wiring to connect it all. There are a number of ways to perform this conversion, depending on budget, but the basic idea is the same: two extra wires are needed per door mirror to connect them to the new mirror switch. The difference in the methods is in how everything is wired up; it can be either plug-and-play with a few extra mirror features or it can be basic power folding done as cheaply as possible or anything in between. This DIY is going to discuss mainly the PnP method of wiring up the mirrors, but it should still be useful for the more basic installs as well.

Parts Needed
Getting these parts in the US is possible, but they aren't exactly easy or cheap to get. Most of the parts in this DIY are only available in Japan, while some of them are available in Europe, but if ordering from the US it’s probably best to get them all from Japan. I get most of my JDM only parts from by using their online unlisted parts inquiry form. There are only three spaces for three parts on the form so you'd have to send a few inquiries to get all the parts you need. It'll usually take a business day or two for them to get back to you. They will recognize that all of the inquiries are from you and email you a link with all of your parts together on one page. Link to the inquiry page is below:

Optional for a Plug-and-Play Harness
For the plug-and-play install as I have outlined in this DIY, I used these parts to make my harness to connect everything together. This method makes for a nice, clean install with the benefit of a few extra mirror features as well. The Honda Access parts are listed in the CR-Z “Interior” page on, so no need to send an inquiry if you are buying your parts from them.

Honda Access Auto-Retract Door Mirrors (08V02-SZT-000) – This enables the power folding mirrors to automatically retract upon locking the car and extend when the key is turned to accessory. The harness in this kit is useful for this conversion because it has a connection to the mirror switch with wiring that can be modified to enable power folding. There are also bits of leftover wiring to make the driver side door harness to connect the mirror to the main harness. This is a JDM only part.

Honda Access Reverse Tilt Passenger Door Mirror (08V08-SZT-000) – This enables your passenger side mirror to tilt down when reverse gear is selected. The harness in this kit has connections to the passenger side door harness and also has an unused connector pair with wiring useful for constructing the driver side door harness. This is a JDM only part.

Passenger Side Door Harness (32752-SZT-A10) - For a complete PnP install, I actually bought a USDM passenger door harness to sacrifice for two wires with the correct pins in order to connect everything through the OEM connectors on the passenger door. There are only enough pins to salvage from the two Honda Access harnesses to make one complete door harness, so this was only option to go that extra mile for everything to plug in using only stock connectors. Another option may be to try to get a LHD EDM passenger door harness and just swap complete door harnesses, since you are buying a door harness anyways; that might be pretty difficult to obtain for those of us in the US though. Otherwise, you can just bypass the door mirror connector and tap directly into power folding wires on the mirror harness for a 95% PnP install.

These are the install manuals for the Honda Access kits that are used in this DIY. They are both in Japanese, but still do a pretty good job of illustrating how everything connects and gets routed through the dash. They also roughly show how all of the trim pieces are removed on the dash, so it's pretty thorough in illustrating what's involved with installing the harness in the dash.

Tools Needed

Basic Wiring Tools – Whether you are making a PnP harness or just running wires for barebones power folding, you will need to be able to splice wires, crimp connectors, etc. If you don't already have this stuff, you probably don't have the experience to tackle this project either...
Interior Trim Tool Set - You'll be removing a bunch of interior trim pieces and these will make it a lot easier.
Small Precision Flathead Screwdriver Set – These are needed to remove the larger pins from the harness connectors.
Small Needles – Some of the connectors use some really small pins and you’ll need a few of these to depin them.
Flathead Screwdrivers
Phillips Screwdrivers
T-25 Torx Bit
10mm Socket
8mm Socket
Small Zip-Ties
Extra Wiring – Preferably the wire colors should be GREEN and YELLOW.

Construction of the PnP Harness

Construction of the PnP Harness (Optional)
The two Honda Access kits are basically combined so that all the power folding connections to the mirror switch and door harnesses are made though a plug-and-play harness. This makes for a real clean install and requires no modification to your dash harness.

These are the two harnesses before they are combined shown below:

The JDM Reverse Tilt harness and the JDM Auto Retract harness before combining. Wiring from a sacrificed USDM passenger door harness in lower right.

Passenger Door Connector on the JDM Reverse Tilt Harness
First, you'll need to reconfigure the JDM Reverse Tilt Harness to work with USDM Vehicles, which I have already outlined in the DIY for reverse tilt mirrors. While reconfiguring the pins as per the DIY linked below, you'll also want to extract the small GREEN and YELLOW pins from the WHITE 23-pin female (plugs into the vehicle harness) connector as well. Do not confuse these with the large GREEN and YELLOW pins on the connector. Leave the GREEN and YELLOW wires on the other connector that plugs into the door harness in place (the one with foam on it), as you are using these to connect power folding to your passenger door harness. I completely removed all electrical tape from the entire harness and re-loomed it with my own wire loom, since I had to integrate the power folding wiring into it anyways. When you are done with the pin reconfiguration, you should have only the ends of the GREEN and YELLOW wires free from the passenger side connectors, as shown below.

The JDM Reverse Tilt DIY linked below details on how to depin the connectors, so use that if you need help to get the pins free from the connector. Please become very familiar on how to depin before attempting this as you can damage the connectors if you are careless. Read both DIYs entirely before attempting! Also do not attempt depinning unless you have the proper tools, as this will damage the connectors as well!

Driver's Door Connector on the JDM Reverse Tilt Harness
There is a good amount of "vestigial" wiring in the JDM Reverse Tilt Harness that can be used to construct a PnP driver's door harness connection. The GRAY 8-pin fuse box connection allows for multiple Honda accessories to be daisy-chained together, so there is actually an unused GRAY 8-pin male connector along with a blank GRAY 8-pin female connector included. Should you have an accessory that daisy chains with the fuse box in this fashion, as long as the modified power folding harness is at the end of the chain, then the missing wiring shouldn't be a problem.

  1. On the GRAY 8-pin male fuse box connector, depin the GREEN and YELLOW wires. Leave the PURPLE and WHITE in place. Optionally the RED and BLUE can be removed as they aren't needed for this harness.
  2. The extra GRAY 8-pin female connector will become your power folding circuit connector for the driver door. Depin the RED and BLUE if you removed them from the fuse box connector. Leave the GREEN, YELLOW and WHITE in place.
The fuse box side of your JDM Reverse Tilt harness should look something like this:

Driver door connector in the middle with green and yellow wires depinned from fuse box connector on the left. Red and blue wires removed. Blank connector used for the driver door harness shown in the lower right.

Mirror Switch Connector on the JDM Auto Retract Mirrors Harness
The mirror switch connectors are the two WHITE 13-pin connectors on the JDM Auto Retract Mirrors Harness. One is a male pinned connector and the other is the mating female pinned connector.

The GREEN/BLACK and YELLOW/BLACK wires need to be depinned from the the WHITE 13-pin male connector which is shown in the image below. Pull these wires from the loom so that they branch out from the junction in the harness.

GREEN/BLACK and YELLOW/BLACK wires depinned from the WHITE 13-pin male connector body shown on the top.

Combining the Harnesses
The two harnesses are now combined into one harness that enables the power folding mirrors to operate in addition to the features that the two harnesses offer separately. The harnesses both have a junction by where they plug into the fuse box, so this can be a good place to start to interweave the two harnesses together. I used some zip ties and some electrical tape to secure them together, in addition to "weaving" the wires into each other. Ultimately you want the two sets of GREEN(/BLACK) and YELLOW(/BLACK) wires to run down the length of harness that extends across the dash to the passenger side door connectors. You might want to test fit the harnesses on the vehicle before combining them to see how everything connects together. This may affect how you want to weave everything depending on how much slack you have for each connection.

When the two harness are combined you should get something like this:

Now the ends of all the GREEN(/BLACK) and YELLOW(/BLACK) wires with naked pins all need to be cut off with sufficient length to reuse the pins and wiring to construct the door harnesses in the final section of this DIY. The cut ends of each color on the combined harness need to all connect to each other: the GREEN and GREEN/BLACK wires are connected to each other and the YELLOW and YELLOW/BLACK wires are connected to each other. Here you will need to add lengths of wire to make the connections to passenger side of the harness. I suggest using GREEN and YELLOW wires to keep everything consistent. I soldered my connections and heat shrink wrapped them, as shown below, but you can use whatever method you feel comfortable with.

GREEN and YELLOW mirror switch wires and driver door wires soldered and wrapped to wires going to the passenger door.

Start with the fuse box side first and then tuck in the two wires into your wire loom, progressing towards the passenger side. After tucking the extra GREEN and YELLOW wires all the way to the passenger side of the harness, make your cut so you can tuck everything away into the loom once you make your butt splice to the GREEN and YELLOW passenger door wires. Once everything is spliced together and tucked away, your harness should be ready to install into the vehicle!

Mirror Assembly Conversion

Mirror Assembly Conversion
The mirror frame and mirror wiring harness need to be replaced in your stock door mirror housings to enable them for power folding. The mirrors need to be removed from the door to swap out the frames and new harnesses.

Door Trim & Mirror Removal
  1. Roll the windows down.
  2. Remove the trim pieces at the front and rear of the door glass.
  3. Remove the trim piece behind the door handle.
  4. Remove the cover inside the recess aft of the window switches.
  5. Unscrew the screws exposed in the two previous steps with a Phillips head screw driver.
  6. Remove the window switch assembly by gently prying it out with a trim tool and unplug it.
  7. Unscrew the screw exposed by removing the switch assembly.
  8. Carefully pry off the door trim piece using trim tools. There are (8) green clips holding it in place. There is a slot on the underside of the trim panel where you can start. Some of these clips may break, so having replacements would be a good idea. Unplug the courtesy light as you pull the door trim free.
  9. Unplug the mirror harness from the door harness.
  10. Pop out the mirror lens now while you have it secured to the car. Use a trim tool wrapped in cloth to gently pry it up from the bottom. Carefully unplug the mirror heater connections.
  11. Unscrew the (3) 10mm nuts holding the mirror in place.
  12. Remove mirror assembly from the door.

Door Mirror Disassembly
Once you have the mirror free from the car, the objective is pretty simple: switch out the existing mirror frame for the motorized frame and swap the harnesses. Disassembly is pretty self-explanatory and it's pretty easy to figure out without actually following the steps below. Be careful to not scratch the paint on the mirror housing, so have a towel or something under it while disassembling.

  1. Depin the mirror harness connector completely. Take a digital photo of the wire configuration to remember how everything goes back. The wire colors are same for the JDM harnesses.
  2. Remove the red electrical tape from the mirror seal and mirror harness.
  3. Remove the bottom cover on the mirror base.
  4. Remove the (3) T-25 Torx screws exposed from the previous step.
  5. Separate the mirror from the base, carefully pulling the depinned wires through the mirror seal and base.
  6. Remove the (1) T-25 screw exposed from the previous step and remove the adapter piece. This will be reused, so don't forget to attach it to the new mirror frame.
  7. Remove the (4) Phillips screws securing the black mirror bezel to the mirror housing and remove it from the mirror assembly.
  8. Remove the (3) Phillips screws securing the mirror actuator to the frame.
  9. Separate the mirror actuator assembly from the mirror frame and unplug it from the harness.
  10. Unscrew the Phillips head screw on the underside of the mirror housing securing the frame to the mirror housing.
  11. Remove the frame from the mirror housing while unplugging the mirror turn signal from the harness.

Disassemble the mirror down to this point and begin reassembling with the JDM parts. Passenger mirror shown.

Door Mirror Reassembly
The mirror should now be ready for reassembly. It will be reassembled in the reverse order of the steps above, except using the JDM mirror frame and harness. Be sure to remember that the driver's side mirror harness will have a GRAY sheath and the passenger side will have a BLACK sheath. If you switch the sides, the mirror tilt will operate incorrectly. Plug in the the small connector with WHITE and LIGHT GREEN wires to the motorized JDM frame before mounting it to the mirror housing.

When you have the mirror reassembled, repin the loose pins into the supplied connector or reuse your old one if you want. Lots of the wires are different lengths, so snap in the shortest wires and twist the longer wires ones around them to take up the slack, similar to how your original mirror harness is setup. The WHITE and LIGHT GREEN wires can be pinned into the two vacant sockets that are side-by-side on the connector. If you do not have the correct GREEN and YELLOW pins to make a PnP door harness, then you can leave the WHITE and LIGHT GREEN pins loose from the OEM connector to make your own wiring connections.

Once the mirrors are completely reassembled with the JDM parts they can be put back on to the car and bolted down. Leave the door trim off as you need to pull wires through the speaker opening in the next section.

Leftovers... notice how the mirror switch coincidentally plugs into the mirror harness...

Vehicle Install

Installing the Mirror Switch
The instrument cluster surround needs to be removed from the dash to install the new mirror switch. This is secured to the dash only using clips, so all you need is a trim tool to pull it off.
  1. Adjust the steering wheel all the way down and out.
  2. Pry on the instrument cluster surround starting at the left side mode switches and work your way around.
  3. Once loose, disconnect the electrical connectors at the left side as well as the climate control connectors on the right side.
  4. Remove the cluster surround from the vehicle and place upside down on a towel.
  5. Unscrew the (5) Phillips screws from the panel that is behind the mirror switch and remove the panel.
  6. Use a few small flathead screw drivers to release the mirror switch from the cluster surround and remove it.
  7. Place the JDM mirror switch in place and reassemble the instrument cluster surround.
  8. Place the surround back into the vehicle, but leave it loose to make the electrical connections to the mirror switch outlined in the next section. Once the PnP harness is connected and secured, you can then snap it back into place.
**Non-PnP install notes**
If you are opting for a non-PnP install, this would be a good time to wire up your mirror switch connector with two extra wires that have the correct pins. Fortunately, you already have the pins to do this from the leftover parts removed from the mirror. The mirror harness, as I have alluded to in the caption at the end of the previous section, uses the exact same 13-pin connector as the one that plugs into mirror switch. All you need to do is remove two pins of your color choice from one of the mirror connectors and pin them into your vehicle harness at the mirror switch connection. Since none of the pins are actually GREEN or YELLOW, you must choose which one is to be "GREEN" and the other to be "YELLOW". There are two vacant cavities in the mirror switch connector between the RED and the BLACK wires; your "GREEN" wire pins in next to the BLACK wire and your "YELLOW" wire pins in next to the RED wire. Both of these wires need to have a connection to each door mirror, so you'll need to make a junction where two wires split off each wire. Run the wires to each door and use some crimp-on quick connectors or something similar to be able separate the harnesses if need be. Follow along with the rest of this DIY, as well as the JDM manuals, to get an idea of how to wire up your custom harness through the dash and in the doors.

Installing the PnP Harness
If you have created a PnP harness, it’s just a matter of routing the new harness through the dash and plugging everything together. The door harnesses will be made once the main harness is connected and secured, since everything needs to be made to the correct length in the doors. The JDM manuals that are linked under “documentation” should illustrate pretty well how it is routed through the dash as well as some dash disassembly steps in the Reverse Tilt Mirror DIY.

The JDM Auto Retract module needs to be mounted as well as the JDM Reverse Tilt module. Where these mount are also illustrated in the JDM install manuals and explained a little in the JDM Reverse Tilt Mirror DIY. The JDM Auto Retract module mounts above the steering column a little to the right side and the module wiring goes above the steering column from the fuse box along with some of the existing harness that go across the top of the dash.

Also, I'm not really a fan of the zip ties that are included with the two Honda Access kits, so I just used my own small ones to secure everything. Loosely route it through the dash and connect everything before clamping down with the zip-ties.

Constructing the Driver Side Door Harness
With the main harness in place, the driver side door harnesses can now be constructed. The sets of GREEN/BLACK & YELLOW/BLACK pins removed from the mirror switch will be used to connect the mirror harness to the new door harness. The large GREEN & YELLOW pins will be used to connect the door harness to the main PnP harness. You will probably need to add some wire to connect both ends to each other inside the door.

With the dash already dissembled from routing the PnP harness in the previous section:

  1. Roll up the windows by plugging in the previously removed mirror switch assemblies for both doors. You can unplug them again after rolling the windows up and set them aside so they just aren't dangling there.
  2. Remove the door speaker by unscrewing the single 8mm screw securing it and lifting up on the speaker. Unplug the speaker from the door harness.
  3. Unclip the first few zip tie mounts on the door harness inside the door through the speaker opening.
  4. Disconnect all door electrical connectors under the dash. There are (3) on the driver side and only (1) on the passenger side.
  5. Push the rubber door harness boots with connectors through the harness openings in the door jamb into the door cavity and pull it through the speaker opening.
  6. Butt splice the large GREEN & YELLOW male pins extracted from the GRAY 8-pin fuse box connector to some extra color matched lengths of wire.
  7. Pull the new GREEN & YELLOW wire through the door harness boot using a wire coat hanger so that the pins are on the vehicle side of the boot, similar to the picture shown below.
  8. Snap the pins into the empty GRAY 8-pin female connector body making sure that the wire colors correspond to the mating connector on the PnP harness.
  9. Pull the door harness boot along with now (4) connectors, back through the door jamb opening and seat it back into place in the door jamb. Clip the harness back into place inside the door.
  10. Plug the connector in the mating connector on the PnP harness and take in any extra slack by pulling the wires from the speaker opening.
  11. Route the wires along the existing door harness up to the mirror connector and temporarily secure them with tape.
  12. Cut the new wires to an appropriate length to butt splice with the GREEN/BLACK & YELLOW/BLACK pins extracted from the JDM Auto Retract Harness, so that we can snap them into the mirror connector body without too much slack.
  13. Butt splice the pins in the previous step into the door harness.
  14. You can now test the function of your driver side folding mirror. YELLOW connects to WHITE and GREEN connects to LIGHT GREEN. If you left the WHITE and LIGHT GREEN pins loose when you assembled the mirror you can plug the loose pins into each other to test the correct polarity before committing to snapping in; this connector is difficult to remove and depin without damaging it. With a PnP install it should fold in when you lock and fold out when you key the car on. Pressing the mirror switch should activate it now too.
  15. If everything tests out ok in the previous step, snap the loose pins into the mirror connectors with the correct polarity and connect them together.
  16. Loom your new wire and secure it to the existing door harness with zip-ties.
  17. You can now reassemble your driver side door.

Constructing the Passenger Side Door Harness
The passenger door harness can be made from either a sacrificed door harness for a 100% complete PnP install or can be partially PnP, by bypassing the passenger mirror connector, while still being able to plug in at the door connector using the last two bits of pins leftover from the PnP harness construction. These are the two small GREEN and YELLOW pins removed from the WHITE 23-pin female connector on the JDM Reverse Tilt Harness. You can just leave the WHITE and LIGHT GREEN power folding wires loose from the mirror harness connector and use your own means of connecting them together, such as crimp-on quick connects.

The install is similar to the driver side install outlined in the section above, except the wire colors are switched for the passenger side. They are now YELLOW connecting to LIGHT GREEN and GREEN connecting to WHITE. Just adapt the steps from what you learned from installing the driver side harness to wire up the passenger side door harness. Whether you are going 100% PnP or bypassing OEM connectors with your own quick-connects, you should be able to figure this out.

Final Test and Reassembly
Test the function of the mirrors to ensure they are both connected the correct way. One should not fold in when the other is folding out or they should not be both folding out when you lock the car. Once you have confirmed everything is functioning correctly you can start reassembling your door and dash trim back into the car.

Enjoy your new mirrors and reply to this thread if you used this DIY to install them. Thanks!

how much did it cost you?
When I priced it out a few months ago it was these prices:

¥13,320 JPY - Auto Retract Mirror Accessory
¥13,320 JPY - Reverse Tilt Mirror Accessory
¥7,920 JPY - Right Mirror Frame
¥7,920 JPY - Left Mirror Frame
¥5,580 JPY - Mirror Switch
¥3,330 JPY - Right Mirror Harness
¥3,330 JPY - Left Mirror Harness

¥54,720 JPY

This roughly comes out to $680 before shipping and without the optional USDM door harness that I used. Not bad compared to most other power folding mirror conversions AND this includes two Honda Access features on top of basic power folding. I actually got my stuff when they were having a 10% off OEM parts sale, so the prices might be a little more than what I have here. Also the exchange rates can make a big difference as well. I see that both of the JDM accessories are at ¥15,720 JPY right now, which comes out close to $200 each.

At this time, I would expect the conversion cost for the parts and shipping to come out to around $750-$850 for the PnP install and about half that for the "no-frills" install. Maybe one of the forum vendors can get some of these parts from overseas and get a group buy going for this conversion to make it cheaper...

I've done some highway driving over the weekend and I started playing around with folding in the mirrors to see if it had any effect on the mpg. I would set the cruise to 65 mph and reset trip B every 10 miles, alternating between folded and extended. It seemed like a benefit of about 1.5 mpg, give or take. Not too bad! If I drove like this all the time the mirrors will pay for themselves in like 15 years... lol.

Just be sure to extend the mirrors if you need to do any lanes changes. It's really weird to look over at your passenger mirror to merge into another lane and instead see yourself in the mirror looking really confused...
