OK, cardinal93,
You kind of got me here. I be such an electrical drongo that I had my brother do the actual wiring.
I just called him and he simply followed the direction that came with the mirrors - no problems.
It has been awhile since we did the install, but from memory there are two wires to each signal
and these were used to connect to the mirrors. I don't believe the stock signal bulbs were two
stage and there were no running lights. Remember that I removed those ugly-ass stock signals and run only the mirrors.
