I have the Mopar harness on my JK and while it works fine I would like to change the slide in connector at the end of the harness and the extension to the MH to a standard 7 pin connector. My reason for this is that I would like to mount this connector to the bumper so that the extension between the Jeep and the MH is more secure. Also would like to do this so if anything happened to the extension I could just replace with standard parts from any auto supply store.

I have been looking for a wiring diagram of this Mopar connector with pin and color info. Has anyone seen a diagram like this floating around?

Thanks

If you're talking about what I think you are, you'd like maybe a 7 pin at the motor home end and maybe at least a 4 pin , better yet, a 6 pin at the Jeep end, correct? I use, and have used on 9 different Jeeps, a Cole-Hersey 6 pin commercial end on the Jeep end. If I can get the picture to come up, you'll see how I presently have it done on our 2015 JKUR. It's protective of the electrical pins from road debris and more.

I took the seven pin extension cable that came with the jeep oem harness, cut it and connected it to a 6 pin receptacle that I mounted through a hole I drilled in my Rock Hard aftermarket aluminum bumper. Then use a coiled cord I bought from Blue Ox to my coach. Works great

It's the exact same setup as FireUp uses.

Fire up, yes this is what I would like to do. We have a 7 pin connector on the MH so I am wondering if I change the jeep end to a 6 pin receptacle which pin would I be loosing?

Rocky Mountain, we have the Rockhard metal bumper, not sure if I want to try to drill that out so might just use a right angle bracket mounted to the top of the bumper.

Still wondering about the wire colors and pin reference.

We are in Alaska right now and I'm not sure if I have my drawing with me. Give me an hour and I'll dig around and look

MoHoGo,
Without going into all kinds of ways that trailer plugs are wired, here's a real basic idea of what's important, and what's next important. If you test each pin, you'll find or, SHOULD find:

1. Tail/marker (also known as "running lights)
2. Right Turn/Brake (99.99% are wired this way)
3. Left Turn/Brake (" " " " " " )
4. Ground

5. 12V hot (This can be either ignition controlled or, hot all the time)
6. Trailer Brakes (This pin is for when you're towing a trailer with magnetic trailer brakes
7. Back up lights (obvious of what it's for)

The arrangement of those pins in a 7 pin plug, has a standard but, it's not always wired that way. The standard is so that you can go from trailer to trailer and hook up your pigtail to each trailer and be able to tow it with all the functions working correctly. It don't always happen that way.

As for which pin you'll loose, that's really hard to say. If I had to choose which one, I'd say "back up lights". Very few trailers have back up lights, some do, but, it's rare. All my toads, 35 years worth, have all been wired using a 6 - pin plug like I linked on the toad end. About 85% of the vehicles/trucks/motor homes we've owned, have had the 7 pin trailer plug from the factory.

The reason I go with a 6 pin on the toad end is because, when you open them up, you'll normally find labeling of each pin. That really helps when setting things up. A second reason is, they're much more heavy duty than the smaller 4 pin or, 4-pin flat or others. It's my opinion of course.

Hope this goes through

Here is a picture of my Jeep's front bumper with the receptacle flush mounted.

Does the Mopar harness power up the side marker lights on the front fenders when the running lights are on?
