Where can I find a wiring diagram/pinout for the head unit for a 2003 Dodge Ram 1500 with the Infinity Sound System?

To elaborate, I bought an aftermarket head unit for my truck, and want to wire it into my Infinity Amp and 6-speakers. Obviously, I don't have a wiring diagram for the head unit harness, it's made to plug into the factory head. Can someone point out a wiring diagram/pinout so I can just hardwire this and save $40 in cables that won't completely do the trick anyway (the ones sold at Circuit City don't accommodate the Infinity amp/speakers) Asked by LordDamax 57 months ago Similar questions: find wiring diagram pinout head unit 2003 Dodge Ram 1500 Infinity Sound System Transportation > Automotive.

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.

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. Sources: http://www.the12volt.com, http://www.swankautosound.com .

1 Swank_AutoSound, regarding your answer "Look no further...":Thats not all of it... thats for the standard sound system. I have the Infinity sound upgrade which has an amp and 6-speaker system with it, some of the wires in the head unit wiring harness go to the amp (power control, speaker output instead of directly to the speakers, etc) and those are not listed on your post. Happen to have those handy?

Thanks a ton for what you did post, that'll be a great reference for later, but like I said, I need the Infinity info as well.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
