Mark1647545493 Posted January 19, 2014 Report Share Posted January 19, 2014 I'm installing a remote start in a 2004 Trailblazer LT. The remote start is activated from the factory key fob. I have the remote starter programed to start when the it gets 2 negative puleses from the door lock. I have a GMDLBP bypass module installed and I've confirmed the remote starter works by touching the remote starters activation wire to ground twice. My problem is I can't seem to find the wire in the truck that supplies the pulse from the door lock. Any help would be greatly appreciated.

Mark1647545493 Posted January 29, 2014 Author Report Share Posted January 29, 2014 I found my answer and am posting it here in case someone else ever runs into the same problem. The lock wire is at the drivers door module pin B3 (grey wire) in the 24 pin plug. A wire has to be ran into the door to tap into this.
