Help! Does anyone know where I can find the Dodge factory wiring color code for my 1998 Diesel 2500 w/ towing package.
I have searched for hours and found several schematics but really nothing that matches the colors of the wires going to my 7 connector plug. The right and left Turn, running lights were easy to find but none of Dodge's wire colors match the accepted code ( brown, black,white, blue, yellow, green and red.)
Thanks

 

The wires don't match on my 97. I used the factory plug by the emergency brake pedal for my prodigy brake controller it just plugs right up. It makes life much easier.

 

Miles PH:
You missed the point of my request. I already have the brake controller installed I am trying to install a second 7 pin connector to mirror the factory connector at the bumper hitch so I can plug a fifth wheel electrical connector in the truck bed rather than run a wire all the way back to the bumper. The Pollak (brand) socket has standard 7-conductor color coding but Dodge uses non-standard color coding. Surely someone knows which color wire Dodge uses for which function back at the plug socket. ???

Dodge uses their own color coding for trailer wiring harnesses. The best way to figure out which wire is which is to buy a test light and figure them out yourself. Be sure to have pencil and paper ready to write them down.

Whitethunder:
I have tried the usual route of test light but still having problems with a couple of wire colors. Right and left turn were simple to find. Tail lights/running lights were a give me. I have a Dodge red wire that is always hot so I assume it is Battery charge but the Blue wire is hot also from the brake controller. I am assuming the Dodge back-up lights is the violet wire. The common ground (white) is something else because a meter shows conductivity with the other lights grounds making checking that way useless. I always hate to ASSUME anything because ASSUME can easily make an *** (of) U (and) ME. I don't know about you guys but I hate vehicle electrical problems. Thanks.

 

OK try this

CIRCUIT FUNCTION
1 12 gauge black GROUND
2 12 gauge light blue TRAILER ELECTRIC BRAKE OUTPUT
3 12 gauge black/orange TAIL LIGHT (Trailer Tow Relay in PDC)
4 12 gauge Red/Tan* FUSED B(+) (40A, Always Hot, F8 in PDC)
5 16 gauge dark green/red LEFT REAR TURN SIGNAL
6 16 gauge brown/pink RIGHT REAR TURN SIGNAL
7 16 gauge violet/black BACK-UP LAMP

 

Hmmm, I was checking wires this weekend, and my brake controller output was 12v+ also! I'm wondering if the output is hot until a trailer is hooked up, and that's how the controller knows it's got a trailer back there?

Hmmmm...

 

Thanks to everyone who responded. A special thanks to Casey Balvert. PS; Love Ontario, the fishing is great and really fun.

 

any idea why the brake controller's output was putting out +12v?

 

Eskimo:
If you find anything out about why the brake controller's wire is putting out +12v please let me know. I am really curious about that too.

 

A call to Tekonsha answered my question... my truck has a Voyager controller in it that the PO left in it.

The Voyager sends out a "trace signal" which is a minute 12v+ current going out the brake output wire, looking for a ground, to indicate a completed connection to the trailer's brakes. This can be tested by hooking the blue wire to the probe of a test light, with the other lead of the light going to ground. It needs a little resistance of the bulb to work.. my Fluke Multimeter did what it's supposed to...NOT load the circuit.

I pulled the thing out, thinking it was bad... Glad I didn't toss it!!!

I'm gonna test it tonight, and the LED should glow green when I do this...

 

Eskimo is right on. Most controllers send out a very low amperage 12VDC signal on the brake output (blue) wire (actually, no amperage if the trailer isn't connected or a meter hooked to the connector! ) If/when you connect the trailer, a very low amperage trace current flows through the blue wire, through the trailer brakes and to ground - this is what signals the controller that a trailer is connected and illuminates the "connected" LED on the controller.
