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 This wire is rated at 10 amps only. If installing any system with high current outputs, go to battery for 12v.
*2 The BCM is in the drivers kick panel near the parking brake. It has 5 plugs in it, one 6 pin plug and four 34 pin plugs.
*3 Lock is negative trigger thru a 5.3K ohm resistor. Unlock is negative trigger thru a 2.0K ohm resistor. MUST use relays.
*4 There are separate door triggers for each door, they are all in connector 3 at the BCM. The driver door trigger is purple in pin 6, the passenger door is PURPLE / white in pin 7, the left sliding door is PURPLE / gray in pin 8, and the right sliding door is purple / YELLOW in pin 5. Use all four and diode isolate each.
*5 Arm is negative trigger thru a 1.5K ohm resistor, this will also lock the doors. Disarm is negative trigger thru a 9.1K ohm resistor, if use double pulse this will also unlock the doors. MUST use relays.
*6 On the 2.4L use blue/green or blue/tan. On the 3.3L/3.8L use blue/green, blue/tan or blue/orange.
*7 The PCM is behind the driver side headlight. VSS is in the gray plug, pin 66.
*8 The parking lights are negative trigger thru a 2.1K ohm resistor. The headlights are negative trigger thru a 790 ohm resistor. There is a rest resistance on the wire, so MUST use a relay to isolate away from the switch.
*9 A diode must be placed inline on this wire to avoid problems with the dome lights and parking lights.
*10 Hatch release is PURPLE / tan in connector 2, pin 6 at the BCM. It is negative trigger thru a 1.69K ohm resistor. Left power sliding door is PURPLE / blue in connector 3, pin 1 at the BCM. It is negative trigger thru a 1.5K ohm resistor. Right power sliding door is the same wire as the left and it is negative trigger thru a 2.7K ohm resistor. Must use relays.
*11 Accessory is not required for remote start. *12 The second starter wire is negative trigger thru a 180 ohm resistor. MUST use relay.
