well first off the anti theft module is in the center console. All your lock wires and motors wires are there as well as all your triggers.
Lock - pink/black
unlock - brown
lock motor - gray/white
unlock motor - GREEN/ gray
Door triggers which there are 4 of. They all must be diode isolated
Drivers door - green      RR door - GREEN / WHITE
Passengers door - GREEN/ orange LR door - GREEN/ red
Trunk trigger - blue/brown

the factory alarm arm and disarm wires are the same as the lock unlock wires. Good Luck!!
