NOTES:
*1 - This wire will not test when using the headlight switch. This wire is triggered by the DRL system. To meter the wire, start the car with the parking brake set, when the brake is released this wire will go to ground. The BCM (Body Control Module) is located to the right of the accelerator pedal below the radio. The plugs on the BCM face towards the driver side.
*2 - Use TAN for the driver door located in pin B4, use ORANGE wire for the passenger door located in pin B2. Use both wires and Diode isolate.
*3 - The PCM (Power Control Module) is located on the passenger fender. On the 2.2L the wire is in a Black 80 pin plug pin 10 and on the 4.3L the wire is in a RED 32 pin plug pin 20.
*4 - Also found in the BROWN plug at the BCM on vehicles with a factory alarm.
