I retrofitted the '03 signal mirror glass onto my '02 Silverado mirrors. Even though the '02 wiring isn't technically compatible with the '03 and doesn't have the extra plug, it was relatively simple to hook up the mirror signals to the proper '02 wires. The problem I'm having is figuring out which wire to hook the electrochromic feature to. I've looked over the wiring schematics for both the '02 and '03s and still can't figure it out. I had gotten info that this feature operates on 1.5 volts instead of 12 and should be spliced into the ISRV mirror using the pink wire. I tested that lead and it registered 12 volts. This would burn out the electro feature pretty quick. I also tested the pink wire from the BCM and it also registers 12 volts. Either I've gotten info that was incorrect or I'm missing something. Is there possibly an in-line resistor on the '03s? Would you have any info that could help?
