NOTES:

*1 - The driver door trigger is gray/black at the driver door module in the door. The RF door trigger is BLACK/ white at the passenger door module in the door. The LR door trigger is lt. blue/black and the RR is lt. GREEN/ black, they are in a harness in front of the fuse box leading to the BCM rear plug. Use all four wires and diode isolate each.

*2 - The BCM (Body Control Module) is under the driver side dash.

*3 - At the BCM in the purple plug, look at row B, cavity two and three should be open with not wires in then. If you make connectors for these pins you can connect them as a( TYPE B ) door locking system.

Tell me if this looks familiar.
