Does anybody have a pin out diagram or Schematic for the switch. I am most interested in the Dome over ride.
the roadie said:Schematics are in the manuals you can download from this thread: http://gmtnation.com/f23/need-service-manuals-get-them-here-371/
But you may be surprised to find out that the Dome Override is a mere momentary pushbutton that grounds a purple wire on the BCM called "LMP DEFEAT". The function is handled electronically by the BCM.
the roadie said:Does doing that manually do what you want? I didn't know 2002 had that function, but again, it's a bad day I can't learn new stuff about this platform.
Team Dougherty said:I was just hoping to parallel the dome switch. Until I took it apart and found out it controls more that two pins on the back of the assembly and that is a double action switch.

Looking at the schematic, it looks momentary. Wish I had an 02 here to test.
With the headlamp switch unplugged, do pins J and M in the C1 connector have continuity when the over ride switch is pressed?
