The wires from the bcm are the wires that go directly to the door lock actuators. I think they are actually power feeds to the actuators and not ground triggers. I think you need to go into the door and tap the blue wire for the door lock signal. Did you program it for 3 pulses? It is set at 1 pulse for default so as soon as you touch the wire at the bcm if it is at ground you get a start signal.

Here is the wiring diagram http://www.titantalk.com/forums/427255-post85.html

I stand corrected. The pulse you are looking for is a +12v pulse and not a ground pulse. See the follow on posts in this thread for the right answer. I'll leave this post here for the wiring diagram, it may help someone in the future.
