      Does anyone have an alarm and remote start wiring diagram for a 2004 Dodge Ram Diesel? (it's actually 2004 1/2, if that 1/2 a year makes a difference.)  Thank you in advance, it's greatly appreciated.

Both Wires Are Located In A Black Connector Center Top Of Fire Wall. There Are Two Black Connectors, The Correct One Does Not Have A White Insert. *** Tach can also be located at pin 74 behind instrument cluster. |

Diode Isolate Each Wire For Alarm Trigger With The Bands Facing Away From The Alarm/Remote Start Module. Use Only One Trigger For Dome Light Supervision. **** Single Wire Door Lock System See Note #211. Lock Requires A Ground (-) Pulse Through A 867 Ohm Resistor.

 remember to check all your wires with a dmm not a test light!! 
 i take no responsibilty whatsoever for the vailidty of the info nor consequences thereof

      For some reason the software bmf1000d uses actually thinks an 04 is the same as the 02-03 Rams.  They are different.  This is for an 04.
 
 
 04 Ram
 12volts      red (x2)       +       ignition harness 
 Starter      yellow       +       ignition harness 
 Ignition      pink/white       +       ignition harness 
 Second Ignition      pink/lt. green       +       ignition harness 
 Accessory      dk. blue & pink/yel (16 awg)       +       ignition harness 
 Second Accessory      pink / YELLOW (14 awg)       +       ignition harness 
 
 Power Lock      PURPLE / dk. green       -       driver kick, door harness 
 Notes: Lock is negative trigger thru an 820 ohm resistor. Unlock is negative trigger thru a 330 ohm resistor. MUST use relays.
 Power Unlock      same wire as power lock               
 
 Parking Lights+      wht/yel (L), wht/gray (R)       +       harness at top of driver fender 
 Parking Lights-      WHITE/ lt. green       -       headlight switch 
 Notes: Parking lights are negative trigger thru a 249 or 330 ohm resistor. MUST use a relay.
 
 Door Trigger      see notes       -       see notes 
 Notes: The driver door trigger is purple and the driver side rear door is PURPLE / orange. These wires are in the driver kick panel. The passenger door trigger is PURPLE / white and the passenger side rear door is purple / YELLOW. These wires are in the passenger kick panel. Use all four wires and diode isolate each. See DirectFax document 1076 for wiring information.
 Dome Supervision      use door trigger wire
                  
 Factory Alarm Arm      PURPLE / lt. blue       -       driver kick, door harness 
 Notes: 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.
 Factory Alarm Disarm      same wire as factory alarm arm      
         
 Tachometer      dk. blue/gray       ac       PCM, orange plug, pin 34 
 Notes: The PCM is on the passenger side firewall. On diesel models the tach wire is at the ECM on the lower driver side of the engine, 60 pin plug, pin 24.
 Wait to start      see document 1091               
 Brake Wire      WHITE/ tan       +       brake pedal switch 
 Parking Brake      dk. GREEN / WHITE       -       parking brake switch 
 Horn Trigger      dk. GREEN/ purple       -       steering column 
 Immobilizer Bypass Module:     Required: Yes     Type: Sentry Key     Part #: 555C or 555U
 Notes: Only vehicles with gray keys have the immobilizer.

      YES.  2004 has a totally different wiring diagram.  I've done several 2004 ram pickups lately and they are definitely different from 02-03. The parking lights is WHITE/ Grey .   NOT the Whie / YELLOW The WHITE/ grey will flash all of your parking lights. JWorm has the correct wiring diagram. John
