I am installing a remote start system with lock and unlock in my 2003 doge ram quad cab, and I am having trouble determining wich wires I need to hook for my lock and unlock?? Which wires for the flashing parking lights,??? and the wires for the hvac so it will run while the truck is started??? Any and all help will be greatly appreciated, Thanks Kevin

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. *8 Diesel tach wire use gray/black in the black plug at the PCM. ------------- Jeff

Jeff, I was looking through all the paperwork you sent, you would not happen to know which wire I would need to hooh up to the HVAC would you??? When the truck starts I have to have power to an hvac wire to make the cooling and heating systems operate. I love this printout it is very detailed and very accurate. Thanks again, Kevin

Jeff, I got the whole thing installed. The orange wire for the hvac I found and hooked up which controls the compressor, I can not seem to find a green wire to hook up for the blower?? I found a green wire but it is a chassis ground ??? Thanks Kevin

Both IGN wires need to be energized as well in order for the blower motor to work. There should be a GREEN wire in the harness( it may be a dark green ).
