Four flat to 7 round connection

I bought a CRV already wired up and demco baseplate installed, but as I hunt for the MH to toad wiring connection I'm confused.

The RV or course has a 7 way round...the CRV has a four flat connection, but what I can't find is a cable that converts....

While they exist, they do not seem to in this configuration. The CRV has a four flat with 3 female and 1 male (which appears to be "vehicle side" as opposed to "trailer side" which would have 3 male and 1 female.

I cannot find a four flat with 3 male 1 female end to 7 round coiled cable at rv end?

    When you cut the wrong end off, do not cut them all at the same length. Stagger the cuts so it's easier to tape them back up.
  • I don see one in the clicks above but you could buy the adapter and then change the flat 4 to the right end. That or make your own cord which wouldn't be as easy.

    Hi,

    The three female and one male ground connections are actually the tow hitch side of the wiring connection. You will need to change that connector to the 'trailer side' of the wires, so that you have 3 male and the ground will be female.

    Then you can use a normal adapter that are sold at all boating supply, U-Haul, most RV supply stores, and places like E-Trailer.com. eTrailer.com

    To convert your car from what is there to what you need, just buy a 6" long wire that has both connectors. Cut the wire in half, and install the side that you need using blue 'butt' connectors.

    Good luck!

    Got it, thanks...I was hoping there was an even easier solution :)

    Google knows all... :) :) Easy and no wiring required.


    Oh I've tried that, but the issue I am having is all of the adapters I can find have the opposite end that I need in the CRV side. The four flat end I have on the CRV side is the same "vehicle end" available on those adapters. I need something that has a four way with the 3 male one female end- to 7 way. All I can find is 3 female/ 1 male to 7 way.
