Please help me understand... I found the "extra" harness (probably for the BRZ auto-dimming mirror?) and I found the 3 wires you described. I checked for voltage on them. I got 0 on blue, 0 on white, and 0.06V on the black wire. I was touching off on one of the body bolts inside of the door for ground. I checked the lamp wires and found 12V, so I had a good ground. I did this with the key both ON (RUN) and OFF.

I am wiring in a Valentine 1. My understanding is that I am looking for switched 12V to tap into, right? Did you find 12V on that "extra" harness?

Thanks.
