Does anyone know where to find the multiplex wire in the 07 its suposed to be purple/brown and i cant locate it!!!

 

purple/brown MUX wire on an 07

Remove the lower steering column shroud... my notes say .....

*2007 Dodge Ram Pick-Up:
MUX wire can be found in SKIM harness above ignition cylinder.

The purple/brown MUX wire will run from the ign switch to the transponder ring around the key cyl..

this wire does NOT run down the steering column so you will have to get it up closer to the wheel ...

hope this helps let me know if you have any questions i've done quite a few of these trucks .... good luck

Chris

 

ok thankyou i will try and find it

 

welcome man... those trucks can be a PITA ... but you'll get it what security module are you using??





To Ramdriver15 ..... here is a diagram of the relays you would have to wire up if you choose to DIY.... FYI lock wire is orange/purple and unlock is pink/purple.. here ya go ..

 

thanks but im using a idata blade and it does everything through data wires in the truck

 

I have a 1989 dodge ram w-250 ctd and i was wondering if anyone could help me find a wiring diagram for this truck. I found one for the 92 ctd and i don't know how much dodge has changed the wiring. Any help is appreciated.

 

Constant 12V+ Red Ignition Switch Harness
Starter Yellow Ignition Switch Harness
Ignition Dark Blue Ignition Switch Harness
Accessory Black/Red or Blue/Orange Ignition Switch Harness
Tach Black/Gray Or Gray (-) At Coil
Brake Switch White Brake Switch
Trunk Pin n/a
Parking Lights Black/Yellow Light Switch
Hood Pin n/a
Factory Disarm n/a
Door Trigger Yellow (-) Driver's Pin Switch
Door Lock Orange Driver's Kick Panel
Door Unlock Pink Reverse Polarity

That should do it for you.

 

thank youi will try this

 

Any one got a lead on a wiring diagram for an 03 5.9L Diesel...would the 04 diagram posted earlier be the same for an 03 5.9L Diesel?

Got an old remote starter lying around which has a 5/10/15 min delayed engine shutdown feature, which should come in handy as a turbo cooler.

Was planning to hook up ONLY those connections which will allow the delayed shutdown feature to function & allow the ign key to be turned off & removed. I'm guessing I'll need to tap into pwr/grnd, starter/ignition, tach & brake pedal.....but NOT the glow plug, door locks, lights, horn, etc.

Notes:
NOTE: For the 2002 Ram 2500/3500, refer to the 2001 techsoft sheet. 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.

Hmmmm.... so I wonder whats up with the word "NOT" for the TACHOMETER wire description

This a typo or is it telling me... "use any wire but do NOT use green/orange" ???

 

That wire wouldnt apply to the diesels anyway, if you need a tach wire i can try and look that up for you.

 

Oh that would be great! The remote starter is going on a 2003 Dodge Ram 2500 Diesel. Was the last schematic posted for a diesel or is the tach wire the only wire that's different?

 

The tach wire for a diesel should be the gray/black wire in position 8 in the black connector on the PCM. Everything I posted should be the same between the gassers and diesels.
