Just grab the "lock motor" wire at the CTM...... it'll make a strong positive pulse every time the doors are locked.

Notes:
NOTE: Chrysler vehicles that use a gray ignition key have an immobilizer system that needs to be bypassed when remote starting. Use DEI part number 555C or 555U. *1 Lock is negative trigger thru a 820 ohm resistor. Unlock is negative trigger thru a 330 ohm resistor. MUST use relays. *2 The Central Timer Module is in the driver kick panel. *3 The driver door trigger is tan in connector 2, pin 15. The passenger door trigger (and rears on the 4dr) is tan/red in connector 2, pin 13. Use both and diode isolate each. See directfax document #1076 for wiring information. *4 Arm is negative trigger thru a 644 ohm resistor. Disarm is negative trigger thru a 1565 ohm resistor. MUST use relays. This wire will also lock the doors, and it will unlock with a double pulse. *5 On the 2.5L/3.9L/5.9L models use BLACK/ gray at the ignition coil. The 4.7L models have an ignition coil for each cylinder, use the wires that is NOT GREEN/ orange at one of the coils. *6 The Powertrain Control Module is on the passenger fender. *7 The 2 door models do not have progressive unlock on the factory keyless.
