Hey....I could only find up to 2002 here: Bulldog's wiring diagrams

I bet the wires are pretty much the same, but someone will probably post 2003 for you. Good luck.

the door locks are possitive your alarm if it is good should be able to adapt to either pos or negative the wire colors are lt/blue and white lock and unlock . in order. this is easy. located at the bcm or mostlikely can be found in the drivers kick. as usual

without the switch on the rear panel you will need peripheral's databus interface dlgm4. Or dei document #1601 and alot of time.

good luck

The AAMP interface sucked when I installed it on my '03 Avalanche. It would only unlock the drivers door and when you started the vehicle the locks would pulse every few seconds.

DEI's best Tech Scott saved me hours of frustration and told me how to directly engage the locks. It should work on alot of the '03 GM trucks and SUV's.

On the purple plug on the back of the BCM directly behind the lt. blue/black and the lt. GREEN/ black rear door triggers put wires into those blank pins. These are your - lock and unlock.
