I found the wiring diagram for the Alero, but I'm having trouble figuring this part out:

*2 Lock requires a negative trigger, and unlock requires a negative trigger through a 1,500 ohm resistor. Must use relays. Must close doors to lock with a single pulse.

What does this mean? I figured out how to lock the car but not unlock. Can someone help me out with this? Thanks!

Eric

Well Eric I havent done it but, it seems pretty straightforward. You would just add a 1.5k Ohm resistor to the unlock wire. If your alarm doesn't have built in relays then you need to use a relay for lock and unlock.
