I can not seem to find the doorpin switch wire on a: " 2003 yukon denali "

I know the wire color is grey/black and it's suposedly running into the curdesy light uder the drivers side of the dash.... but on this truck thier is no curdesy light....

Wondering if somone knows what loom its in so I can find it.... Its kinda a pain because the parking lights wire color is also grey/black....

thanks in advanced,

Amp

This is what techsoft states for 03 yukon.

*1 The driver door trigger is gray/black at the driver door module in the door. The RF door trigger is BLACK/ white at the passenger door module in the door. The LR door trigger is lt. blue/black and the RR is lt. GREEN/ black, they are in a harness in front of the fusebox leading to the BCM rear plug. Use all four wires and diode isolate each. *2 The BCM (Body Control Module) is located behind the headlight switch.

Look for the GREY/BLACK wire between the driver's door and the rear passenger door in the harness going to the rear of the truck. On the Trailblazers without the underdash light, I found the door trigger wire in the same spot. Try this and post your results.

check the black plug at the BCM. the gray black wire i believe. that will be your dome light. this will work for door triggers

or you can grab the domelight wire at the lights in the headliner above the drivers head....i've never yet seen a ST6 chassis with an underdash light and always go to the courtesy lamp at the drivers head...takes all of 5 minutes....

dont know if it would be exactly the same but did a 04 yukon the other day at work and the door trigger wire for the driver and pass door was actually in the door.
