03 avalanche

Intrested in using factory remote to produce three short - pulses to a crimestopper 901 add on.. if its data bus i need to find factory rearm wire for the pulse? customer wants driver one and two memory and thats the only way i can can think to do it.. any help??

Is the Crimestopper a remote starter that uses the factory romotes? I installed a Design Tech unit in my 03 Avalanche that uses the remote from the factory to trigger the starter. To get the pupse signal I tied into the door lock wiring near the fuse panel at the drivers door. If I remember correctly it is a grey wire in the upper left corner of the fuse block. I trigger the remote lock twice in three seconds to start the truck. I retained all the memory functions of the remotes. Hope this helps..
