Adding USB outlet to cig lighter, wire identification help

Nice job. I will confirm that of all the fixes/tinkering/etc. on the Tundra that I done over the last two years that this cig lighter was one of the most difficult head scratchers and pains in the butt just to get a simple bulb in place! I even had to fab up my own bulb.

 

it really is a poor design. my outlet install was a huge pain, and i love it, but would not do it again. going to do the timing belt kit when it warms up a bit, which will take much longer but not as frustrating
