I have hooked up my car alarm-- and it is working. But here's my dilemma: I needed a single wire hookup for the door trigger. (I can go negative or positive trigger) I could only find a one-wire hookup if either/both of the courtesy lights was set to door. Turning off the light/door feature turns off the trigger and the alarm thinks the door is/remains open. The left hand switch Purp/Blue wire and the RH Purp/Pink wire eventually come together through the Purp/white wire that feeds the delay. That's the one I hooked in to; it shows ground when either door is up, and positive when both doors are down AND at least one courtesy light is in the door position. Q: Does anyone have a better way to do this? Other things for future DIY'ers to note: get a negative trigger car-lock feature. It's breeze to hook up. The brown/pink and brown/slate wires going into the door lock module hook up to the lock wires from the alarm. The Brown+slate is the lock, and the brown+pink is the unlock. Next Question. I'm going to do the door-latch actuators from Darryl. Do I have to run wires for his actuators? or can I use the LGW that the Zilla's schematic shows running to the door for the proposed mirror heaters. Thanks! Kevin #4687
