Well that wasn't so bad. Less than an hour's worth of time gets you a function that should have been there in the first place.
All things considered it was pretty easy and I used the stuff they already provided.
For anyone else that wants to DIY their harness to fix the illumination control wiring here is some help:
! Overcomplicated Guide
Requirements:
- Less than an hour's worth of time
- Some sort of small metal pick tool to help push away small metal pieces (image below)
- Solder + soldering iron (though technically you could just mash the leads together and call it a day)
- CANBUS harness
- non-CANBUS harness (to harvest the wires + metal leads)
*Marks optional
It Begins:
To begin, you will be removing the pin from the non-CANBUS harness to use. Locate the pin circled in blue. It should lead to an orange wire.
Insert something thin below the pin, and try to push upwards towards the pin. What you are doing is bending two little metal 'hooks' so that you may safely remove the pin. If you look into the empty hole depicted beneath, you will see how the pin is held in.
You can see in this picture the metal that was bent. Bend it back unless you want your pin to fall out. I just used a small flathead screwdriver bit.
It's okay to cut the orange wire to detach it from the black plug. If you really want to be like me and have a hard time, just cut the wire or continue following the next step.
*You should easily be able to tell that the other end of your now loose pin leads to the black plug. Look into the plug and familiarize yourself with what you're working with.
*Go ahead and use your pick tool now. Hopefully you found one that is small and sturdy. Small enough to fit all the way down into the 'bottom' of this plug. Insert the tool as far as you can down the middle and push towards the plug you will be removing. You will essentially be bending the metal piece past whatever plastic hook it has latched on to.
OR you can just clip off the wire but with how thin it is, I can't guarantee a strong connection. I personally like to work off of what is already there.
*Now, on your ACTUAL harness, go to this white plug (it leads to your CANBUS). Locate the wire. Use your pick tool and simply press down on the metal where is shown in this picture. It's actually really simple to remove this if you just apply a light tug while pushing the metal down.
*Now, it's just as simple as inserting the pin to your ACTUAL harness (double check your orientation). If it does not fit snug, then double check to make sure you bent the metal back into place. Also verify that the pin is not bent once inserted.
*
Now take the now loose orange wires from your ACTUAL harness and fasten them together in your own preferred ways. As mentioned, you can either take your metal and mash it together, or you can solder it like I did. It's just connecting two wires together - you don't have to be too creative. Feel free to be safe and cover the exposed metal with shrink tube or electrical tape.
Zip-tie everything down all organized and neat if you don't want to risk wires tangling / sliding around.
You're done! Don't forget to toggle OFF the manual backlight control in your settings. I hope this was helpful.
