For the Passlock III, I suggest using a bypass module for ease of installation. Use a PKG-4 bypass module here: https://www.velocitymotorsport.com/security/gmc_transponder.htm. Here is the wiring diagram for this car:

Notes:
NOTE: This vehicle is equipped with the pass-key III immobilizer. Use a PKG-4 bypass module here: https://www.velocitymotorsport.com/security/gmc_transponder.htm. to bypass during remote start mode. *1 The tan is located in the drivers kick and catches only the drivers door. The dark/blue is located in the passenger kick panel and catches all other doors, must diode isolate these wires. *2 Located at a 10 pin plug on the front of the drivers strut tower. There are two dk.green wires there, use the one in the corner of the plug. *3 The PCM (Powertrain Control Module) is in the air cleaner assembly.
