Yes, that little bit of ambient lighting is actually very nice to have. I think my next lighting jobs are going to be lights in my center console, lights under my running boards (that only come on when the doors unlock like the ones on the running boards do - puddle lights), and a light or two UNDER THE DAMN HOOD! I can't believe Toyota didn't put a work light under the hood. I guess it's because they never need to be fixed! :bravo:
Anyway, I don't have a write up per se for doing the overhead console swap, but I can definitely give guidance. The first thing you will notice when you get your Lexus OH, is that the connector receptacle is different. At least they ran wires to it and it's not part of the assembly like on ours. I removed the receptacle from the OH and to keep as much length as possible, removed the pins from the recept, then cut the pins off. It's just a habit I have to ensure I have as much wire as I may possibly need.
Ok, Then I went through the tedious task of identifying what every wire did (but you won't need to since I already did). Assuming your 4runner has a sunroof, there are 3 additional wires on the Lex OH. These wires are for the LEDs for the ambient lighting (12v & ground), and a ground for the door open switch. On another connector though is the microphone wiring.
You may choose to wire it up a different way completely. However, this was the way I chose to do it in case I ever wanted to reinstall an original OH again. Thinking back, I probably would have done it differently by simply putting a mini-molex on it for all of the wiring, to include the microphone wiring.
I again went through the tedious task of identifying what every wire did. Then I used a Dremel to cut the plastic connector receptacle off of the 4Runner OH (it is actually a molded part of it). I used a sanding drum to smooth it out completely. With the 4R recept removed, I prepared it to attach the Lex wires and pressed on with soldering.
The picture I have included is at this point.
I then cleaned it up with alcohol, put some epoxy over it, and wrapped it. The wires for the LEDs, door open, and microphone, I originally put in a D-sub connector, but later changed out to a mini-Molex connector. Obviously, just check twice & even three times to make sure the wires match up. Not only will you cause yourself headaches, but you can burn something up.
Which leads me to my next comment:
Do this at your own risk!
