Tested the interior fuse box - #18 and #19 are Charlie Sheen #Winning - Page 4 - Honda CRZ Forum: Honda CR-Z Hybrid Car Forums

wiring up some led's to one of these open fuse slots. i calculated that it will pull around 3 amps (23 milliamps per led bulb). every piece of literature i find says to use 16 gauge wire, but that seems a little thick for a few led strips... any1 know what size wire is appropriate?

I am no expert but when I ran LEDs before a 22g wire worked fine. no in line fuse. a direct connect to battery with switch. all neg ground to body.

3amps is a fair amount... I wouldn't use smaller than 18 guage, and always use a fuse :-) you never know if that wire will get pinched and touch metal.

Yeah, I will definately be using a fuse and a toggle switch

I didn't test the "Backup" one since I really don't understand why Honda's engineers uniquely labeled it with a special box around it. I just assume it'd be a bad idea to mess with it.

Yes, I accidentally discovered that fuse 1 (Back UP) not working is a bad thing. It blew when I plugged a GPS device I was testing into the OBD-II port (it was damaged and in essence shorted anything it plugged into- so I learned the hard way). Losing that fuse killed the IMA, traction control and emissions system, plus the entertainment system, remote locks and a handful of other things stopped working. Thankfully, replacing the fuse fixed the IMA right away and everything else after a few short trips.

I'm gonna finish up this mod this afternoon, weather permitting.

I'm adding a power outlet, so that if the need arises, I can charge my cell phone or what ever while the car is not on.

A special thanks goes out to holeydonut for the write up.

I'm gonna tap in to fuse position #46, using an add a fuse gizmo, and a 10A fuse.

Exco

Does anyone have a picture of their setup? For instance I am wanting to tap into an ACC/ON fuse, so I assume 18 or 19 for my radar detector hardwire kit. Can someone recommend what mini fuse addon kit to get and use for this setup? Also, would I need a 10 or 20 fuse for it? For your standard Escort 8500/9500 radar detector. Any help would be greatly appreciated.

10 amp is a lot more than you will need for the Escort.

Well, I tried to use fuse #5 (BACK LIGHT) and found that it was on regardless of whether I was in reverse or not.

It was on whenever the car was in ACC or ON, though it may be a timed circuit that controls the interior lights in the back.
