NOTES:

*1 The PCM is located under the hood on the passenger side inner fender at the firewall. On the V6 the wire is located in pin 54, and on the V8 the wire is located in pin 35. *2 The BCM is located in the passenger kick, just in front of the blower motor. *3 The tan will unlock the drivers door and the gray/black will unlock the passenger door. Wire each as a 5-wire system with separate relays. See direct fax document # 1052 *4 Not all models include this circuit. *5 Use gray/black for the drivers door and BLACK/ white for the passengers door. Both triggers must be diode isolated. *6 Some models are equiped with a factory alarm. The only way to disarm these alarms is with the factory remote or turning on the ignition. To turn off the factory alarm, see "direct fax document #1051".
