LED PWM controller, dimmer integrated
 

Been playing around with this idea for a while. I swapped out almost all my bulbs to LED. I put a PWM controller in the gauge cluster to dim those already, but I don't like that I can't control it since I didn't put a hole in the face of the cluster. I wanted something that would work and look like stock. If the green connector doesn't slide in I'll just remove it completely and solder right to the board, I may wind up doing that anyway. This all isn't done yet, but it will dim like stock and still work the ground for the interior dome light. I will wire the controller to the copper traces in the dimmer so when the mating connector is plugged in it will power the controller and the output will power the lighting circuit. I will have to remove the transistor and jump B to C on that connector to make it all work.

Good thinking. That is the primary reason why I haven't wanted to change to LEDs. I'm interested to see how this works out for you.
