Adapter for 7 pole rv to 4 pole round?

[brandonrv]

I got my jeep wired so that I can plug directly into the front of it when I'm towing. Problem is they installed a 4 pole round connector in the front, but I've got a 7 pole RV connector on the RV.

Anyone know an adapter for this or do I have to go get the RV wired for 4 pole round now?

A local U-Haul that does trailer hitches wired mine for me.
I bought the 7 pin plug, they put it on my existing cable.
It was easy and they did not even charge me for it.

brandonrv,
Yes Sir, they make adapters for 7 pin RV plugs to any configuration you want, 4-pin flat, 4-pin square, 4-pin round, 5-pin round, 6-pin square and more. DO NOT CHANGE THAT PLUG ON THE RV!! It's most likely wired by the factory and is well done and to national color coding and pin placement. It might be useful at a later date when you might wand to hook up a larger trailer etc.

One of the first things you must do is, make sure that the wiring/pin arrangement in your seven pin RV plug is configured so it will match up to the 4-pin round correctly. We've owned four different RVs, (2) Class Cs, and (2) Class As. All four came from the factory with 7 pin plugs. As did and does, about 99.9999% of all the pickups sold in America.

Most of your adapters can be found at Camping World, or any other well supplied RV Supplies outlets. One of the nice things to have around is an "LED", 7-pin plug checker. I just got one from a local swap meet for about $5.00 and man, is it great. You can check the out put right at that plug and see if all is good every now and then.

Thanks, scott. Maybe that's the problem with my adapter. The pins don't match up. I'll look at getting one of those 7 pin testers. Maybe I can figure out how to rewire it.

I can't.. I'm sure I could pay someone to do that. I took my jeep to a motorhome dealer to do the wiring for me. Figured they knew what they were doing.

Got home realized it doesn't hook up. Got online can't find many adapters. Found that Hopkins one and bought it. Doesn't do the trick.

This 4 pole round is sort of a mystery.

Assuming you already have a cable with 4 pin connectors on each end?
If so, just pick up a 7 pin plug and change the one on your existing cable.
Eliminates adapters that might be an additional failure point.
Walmart, auto parts or U-Haul should have the 7 pin plugs.

Can you remove the 4 pole round and wire in a 7 round?

We also have 7 round on the mh, 4 round on our car. We bought this. Sorry can't do a linky.

[brandonrv]

Yeah I got one of those already and it doesn't work. LIghts in the jeep are not responding.

Something funky going on here.

For some reason Motorhome Manufacturers tend to put on 4 round connectors. Thus your toad was wired to match the industry standard. Most utility trailers are wired with 4 way flat connectors. Not sure why motorhomes must be different. However you can make your own with the appropriate connectors. If you must buy, Hopkins has an adapter cable part no. 47043.
