Additional Info:
Note : Jeep vehicles that use a gray ignition key have an immobilizer system that needs to be bypassed when remote starting. Use Commando part number TransMod. Note : Use Commando part number JDL door lock interface control module.This will control door lock, unlock, arm, disarm, dome light supervision and more. [1] Use orange/black and pink/black at the drivers door lock switch to lock and unlock the drivers door. Use orange/purple and pink/purple at the passengers door lock switch to lock and unlock all of the other doors. [2] The dk. blue/pink will flash the hazard lights. They will flash even with a latch input to the wire. The parking lights can be activated by using a 1300 ohm resistor to ground on the yellow headlight wire. [3] Use a 330 ohm resistor to ground for headlight activation. Use 80 ohms to ground on the same wire to operate both the headlights and parking lights. [4] There are 4 separate door triggers wire, one for each door. Use all 4 wires and diode isolate each together. The drivers door is tan/red at the drivers door lock switch. The passenger door is tan/red at the passengers door lock switch. The drivers rear door is tan/orange and the passengers rear door is tan/yellow at the BCM. [5] Factory alarm disarm requires a 463 ohm resistor to ground on the wire at the drivers door lock switch, you MUST use a relay. [6] The 4.7L motor has a separate coil for each cylinder. Go to any coil and use any wire that is NOT dk. green/orange. On the 4.0L motor use any of the tan/stripe wires at the coil pack, or go to one of the fuel injector and use the wire that is NOT dk. green/orange.
