Notes:
NOTE: This vehicle has the passlock II immobilizer system that, when adding a remote start, must be interfaced with. Use DEI part 555t or 555L. *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 fusebox leading to the BCM rear plug. Use all four wires and diode isolate each. *2 The BCM (Body Control Module) is located behind the headlight switch. *3 If Directed module part #456G is not available, refer to directfax document #1601. Upper trim level vehicles may have a door lock switch on the right rear panel. If present use white (-) for lock and lt. blue (-) for unlock.

Notes:
NOTE: For the 2002 Ram 2500/3500, refer to the 2001 techsoft sheet. 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 requires a negative trigger thru a 820 ohm resistor. Unlock requires a negative trigger thru a 330 ohm resistor. MUST use relays. *2 Parking lights require a negative trigger thru a 330 or 1.4K ohm resistor. Headlights require a negative trigger thru a 1.8K ohm resistor. There is a rest resistance on the wire, so MUST use a relay to isolate away from the switch. *3 The LF door trigger is tan, and the LR door is tan/orange or PURPLE / orange. These wires are in the driver kick panel. The RF door trigger is tan/red, and the RR door is tan / YELLOW. These wires are in the passenger kick panel. Use all wires and diode isolate each. See directfax document #1076 for wiring information. *4 This will also do door locks. Arm/lock is negative trigger thru a 2K ohm resistor. Disarm/unlock is negative trigger thru a 480 ohm resistor. Single pulse will do disarm without unlocking the doors. Unlock requires a double pulse. MUST use relays. *5 The PCM (Powertrain Control Module) is on the passenger side firewall. *6 The amplifier is located behind the glove box. *7 These wires may not be necessary for remote start.

Is up to the installer to test all wires with a DMM whenever possible.
