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!

Relay #1 pin 85 neg LOCK trigger from alrm

pin 86 a fused 12 volts

pin 87 ground

pin 30 output to the one wire lock

Relay#2 is set up the same pin 85 gets neg unlock trigger from alarm. pin 87 gets grounded. pin 30 put in line a 1500 ohm resistor, then take pin 30 to the onewire door lock
