EXTRA INFORMATION

NOTE #1: This vehicle may be equipped with CHRYSLER'S ANTI-THEFT TRANSPONDER System (GRAY IGNITION KEY), if so to remote start will require the 791 BYPASS MODULE and an extra Ignition key, to order go to the SECURITY BYPASS MODULE PAGE on this website. NOTE #2; the (-)Negative PARKING LIGHTS are a (-)Negative thru a 330 Ohm Resistor on the 2004 and on the 2005 they are a (-)Negative thru a 590 Ohm Resistor, to connect, See DIAGRAM NOTE #3: the (+) Positive PARKING LIGHTS on this vehicle use 2 Wires, to connect will require 2 extra Relays part # 775, See DIAGRAM NOTE #4; the Door Locks are a 1-Wire System, the LOCK requires a (-)Negative thrua 820 Ohm Resistor and UNLOCK requires a (-)Negative thru a 330 Ohm Resistor, some units will also require 2 extra relays part #775, to connect, See DIAGRAM NOTE #5: the DRIVERS DOOR is a TAN (-), the DRIVERS REAR DOOR is a PURPLE/ORANGE (-), these wires are in the DRIVERS KICK PANEL. The PASSENGE DOOR is a PURPLE/WHITE (-) and the PASSENGER REAR DOOR is a PURPLE/YELLOW (-), these wires are in the PASSENGER KICK PANEL. When connecting to an ALARM SYSTEM, use all 4 DOOR TRIGGER wires and DIODE ISOLATE. to connect, See DIAGRAM NOTE #6: the PCM (Powertrain Control Module) is located on the PASSENGER SIDE firewall, the DIESEL tach wire is a GRAY/BLACK at the ECM (Electronic Control Module) on the lower drivers side of the engine, 60 pin plug, pin 24. You cannot use the Wait to Start wire on this vehicle.For the WAIT to START, use the programming in you unit for the 5, 10, 15 or 20 Second Wait to Start Timer. NOTE #7: For the 2004 model year vehicle, to ARM/LOCK will reuire a (-)Negative thru a 2000 Ohm Resistor and to DISARM/UNLOCK requires a (-)Negative thru a 480 Ohm Resistor. A Single Pulse thru the 480 will DISARM without Unlocking. Double Pulse to UNLOCK. Some units will also require 2 extra Relays Part #775 to complete this circuit, to connect, See DIAGRAM NOTE #8: For the 2005 model year vehicle, to ARM/LOCK will require a (-)Negative thru a 644 Ohm Resistor and to DISARM/UNLOCK requires a (-)Negative thru a 1565 Ohm Resistor. A Single Pulse thru the 1565 will DISARM without Unlocking. Double Pulse to UNLOCK. Some units will also require 2 extra Relays Part #775 to complete this circuit, to connect, See DIAGRAM NOTE *8 On some Full Size Trucks with Climate Control it may be necessary to connect (3) extra Accessory wires. PINK/YELLOW 16 gauge & PINK/YELLOW 14 gauge and the DARK BLUE Accessory #1 to turn on the A/C Compressor.
