Hey Phil,
Have you had anyone inform you that using that resistor inline to make your LED on your mirrors light up when the door are unlock/reverse creates a phantom current draw? it killed my battery within 2 weeks if I didnt drive the truck daily. I only figured it out after replacing the factory battery and the new one went dead, I found the issue by using a 10w 1ohm resistor and using my volt meter to measure the draw, which was around 3.7 ma(.11amps)which over a extended period of time killed my battery.
