Have an older pa with the card plug in style security system,for starter enable.

First question is is this a gm system or after market??

Then how can i bypass it as the bad person who was buying it from me dropped the car off at my house and took the card with him.

Thaks for any help

most of these are aftermarket, and all you have to do is trace the wires, usually underdash, and reconnect where it was spliced in.

Thats what i was thinking thanks a lot
