I just completed the alarm beep mod on my new max, much easier the second time around.

Now I had the idea to use the dome light buttom one my keyfob to turn on and off something else on my car, right now all I can think of is my headlights.

I found what I think is the BCM on the right side of the trunk adjacent to the power antenna, and I hooked up my voltage tester to each wire and pressed each button on the keyfob, and the only change in voltage is when I press the trunk button.

Does anyone know were the part of the BCM that controls the dome light is?

Also, I used my electrical diagrams at the back of the Haynes manual to re-creat e a detail for the alarm beep mod, drawn in cad and in color, but I'm a nubie and I can't post it yet. And I cannot find anything showing wiring to the dome light in the electrical diagrams.

 

the bcm is under the radio
