Notes:

NOTE:  This vehicle has the passlock II immobilizer system that, when adding a remote start, must be interfaced with. Use PLDATA or TBKII for bypassing the Passlock System  *1 The BCM is located to the right of the accelerator pedal below the radio.  The plugs on the BCM face towards the drivers side.   *2 Use tan for the drivers door located in pin B4 of the purple plug, orange for the passenger door located in pin B2 of the purple plug, must diode isolate these wires.  *3 The PCM 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 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.  *5 Also found in the brown plug at the BCM on vehicles with a factory alarm.
