You don't need a Passlock module to do a security system.....it's only for remote start. Not wanting to repeat myself, see this. You have everything in the box to do this car. ------------- Prepare your future. It wasn't the lack of stones that killed the stone age.

If it's got power locks - you'll need a 1500 ohm resistor for them. You'll also need a relay if you want to do driver's priority unlock. You'll need 2 diodes for the door trigger input.
Also, stop freaking out. It's not a life and death situation.

That alarm should be easy - you can reach basically every wire at one point on the car(the BCM). Mount the brain behind the radio/HVAC controls out of reach, and you're golden. Not a hard car at all.

yea i know its gonna be a breeze. ive already located all the wires and such.. but its the stupid cobalts single wire lock/unlck system that is tricky. uses resistors relays and such other than that the basic alarm wiring tapping is a breeze cuz just like u said practically every wire is at the bcm
