Information Please,

Does anyone know if the 1998 Dodge Ram/Cummins Dash light pull switch has a removable trailer wiring harness. Is the trailer wiring harness plug and play. Mine was altered by previous owner. If so can the oem trailer wiring harness be purchased and where?

Thank you, Tom. 

 

I doubt you really want to run a new stretch of wire from the front of the truck.  The closest plug for the bed wiring is under the drivers front tire. to my knowledge that is the only "plug and play" plug that the entire bed wiring goes to.

So your talking about the harness for the trailer plug at the rear bumper right . I think my y2k plugs in back there at the light and wires run to the front for the controller.

I am talking about the wiring harness from the oem push/pull light switch installed in the dash to the aftermarket trailer brake control box.

There should be a oem harness hanging from the oem  light switch that will plug into the aftermarket trailer brake harness, like plug and play.

Is it possible that the 98 Ram 2500 did not have the oem harness when built? I do know on my 98 there are wires hanging down and hand wired and wrapped with black tape and my trailer brakes do not work properly. If there is such a harness available I would happily buy it to save the wiring job.

I thank you members for helping me solve this mess. I did not do it but I have to fix it but I refuse to blame George Bush.

O got ya. I miss read.

I dunno if the 98.

I can chase wires later and take a look since my dash is broken apart anyways

Somebody correct me if I'm wrong, but why would a harness run from headlight switch to a aftermarket trailer brake box...its activated by the brake light switch... don't make sense     maybe I'm missing something

On my 98 the trailer wiring is made into the harness and just has a connector in the back about dead center built into the harness that goes between the tail lights. All I had to do was by the trailer plug with a short harness for a dodge that reaches to the back. If you use there set up you can even get a brake controller that plugs in under the dash and not have to tap into any wires or run any. As I recall the plug and brake controller can be ordered at U-Haul or NAPA.
