All the remote start/alarm related wiring is already stickied in the Audio forum, just fyi.

Hey, here's another tip to add to that wiring diagram up top. When doing remote start use the factory rearm wire from the remote start to trigger a relay to pulse the door trigger wire. This will shut off your lights if you have it on auto mode. You also have must wire the relay to split the door trigger wire if you have an alarm/remote start combo.
