Notes:
*1 These wires will test only by operating the key in the passenger door lock cylinder, not the rocker switch on the door. *2 Vehicles without Daytime Running Lights it is RED / blue. Vehicles with DRL it is RED / green. *3 The driver door trigger is green, the front passenger door trigger is GREEN / WHITE, and the rear door trigger is YELLOW /GREEN. Use all three wires and diode isolate each. *4 On the 4 cyl it is at the data link connector to the right of the steering column. On the V6 it is at the igniter on the passenger fender, below the air filter box.
this is for the 2002 model, I hope that this helps
