I'm installing a car alarm and need a little information on the central locking system. On the alarm that I am installing (performance teknique) they have the three wires (normal open, common, and normal close) I need to figure out where these wires need to be connected to. I found the wire harness under the dash that has the wires going into the BCM but need to know where the three locking and three unlocking wires go. Can anyone please help me? It would be much appreciated, thanks!

If I remember correctly, that year Blazer has positive trigger locks. White and light blue colored wires I think.
Common --> +12volts
normally closed ----> not used
normally open ----> to the lock and unlock wires in the Blazer.

thanks Jworm!
Do you have any information on the door trigger wires? I found a white (-) in the BCM but there are two wires from the harness one for + and the other negative, does the positive go to 12v? Also, what are the two wires labeled oil way in/out?
Thanks a lot man. You are a great help.
