Adapter for 7 pole rv to 4 pole round?
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. ...

Yeah I've got the adapter. Looks like the 7 pin side is right but the 4 pin side is not right. I guess I should try to wire it myself. How can I tell what the 4 pin is set up to on my Jeep? I assume I just have to match colors?
Lay a battery on the ground after first establishing which pin is ground with an ohmmeter. Connect the neg side of the battery to this ground pin or just try the toad frame. Then touch each pin other than the ground with the battery pos to see what lights up on the toad. Make a drawing of same.
The same can be done with a meter at the end of the umbilical and turning things off and on in the coach. Whichever is easier can be changed to match.
