Does anyone have the wiring diagram for the 2003 ram? I am installing an alarm with door locks, light flash , and illuminated entry and an entire stereo system? This info would save me lots of time testing.
I have been working on 2003 ram 1500 and 2500 and they are the same as in 2002.
refer to those chart

Yes I'm Back 2006...
Here is the information for the 2003 PU;

| POWER LOCK|WHITE/ green *1 |- |driver kick panel |
| POWER UNLOCK|same wire | | |
| LOCK MOTOR|tan/pnk or tan/blk | |driver kick panel |

| RADIO SWITCH|BROWN / red |+ |radio |
| RADIO ILLUMINATE|ORANGE / blue (dimmer)|+ |radio |
| LF SPEAKER|lt grn/rd-lt grn/grn| |radio or amplifier *6 |
| RF SPEAKER|lt blu/pu-lt blu/blk| |radio or amplifier *6 |
| LR SPEAKER|wht/red - wht/blk | |radio or amplifier *6 |
| RR SPEAKER|tan/pur - tan/blk | |radio or amplifier *6 |
Notes:NOTE: Chrysler vehicles that use a gray ignition key have an immobilizer system that needs to be bypassed when remote starting. *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.
