anyone?? Won't hooking up the factory alarm rearm wire to my door trigger cause my alarm to trip when the remote start is turned off or prevent it from arming since it will think the door is open each time the lock/arm button is pressed? Just looking for a little more guidance so I can understand before I rip the dash apart. thanks so much!

yes, actually it will do all the negative things you describe. in order to prevent that from happening use the diagram below.

the diode will still allow the negative trigger from the door pin to operate as normal but will block the negative pulse from the factory alarm rearm wire from reaching the alarm door trigger wire. you must place the door trigger wire from the alarm on the BLACK / YELLOW wire between the door pin and diode. place the pulse after remote start wire on the yellow/black wire between the other side of the diode and the bcm.

Ahh diodes! That makes sense....being more of a plumber type, I am guessing a diode works like a checkvalve when it comes to water! Any certain type of diode I need to use? Thanks again!
