I am looking for a wiring diagram for a 2003 GMC Yukon Denali. Any help would be greatly appreciated. Thanks.
12 volts - red & RED / white (+) found at ignition harness
starter - yellow (+) found at ignition harness
ignition - pink (+) found at ignition harness
2nd ignition - white (+) found at ignition harness
accessory - orange (+) found at ignition harness
2nd accessory - Brown (+) found at ignition harness
power lock - Use DEI part number 456G(this will control lock/unlock/arm/disarm(of factory alarm))
power unlock - Use DEI part number 456G(this will control lock/unlock/arm/disarm(of factory alarm))
door trigger - heres where it gets fun.....*
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 (-) polarity NOTE: you must diode isolate each wire.....which means u will need 8 diodes....you need to place a diode in line with each wire...and then diode isolate the - door trigger input wire off the brain with 4 diodes at the end...place them below the diodes in line with the trigger......its tough beleive me |
trunk trigger - pink/black (-) polarity found at BCM(The BCM (Body Control Module) is located behind the headlight switch under the driver side dash.)
brake wire - white (+) polarity found at brake switch
tachometer - NOT PINK (use an uncommon wire) at any fuel injector
parking lights - Brown (+) polarity found in DKP or u can try finding it at the switch
factory arm/disarm - Use DEI part number 456G(this will control lock/unlock/arm/disarm(of factory alarm))

Using the 456G will greatly simplify the door trigger. It has an input for the dome light from the vehicle then an output to connect to the alarm. It will interupt the door trigger for a few seconds when you remote start, because the domelight turns on upon disarm. Turn door trigger error chirp off to prevent the alarm from giving an extra warning chirp upon arming.
