Well, there is a 7-pin round RV plug with a 4-flat end on it. Then there are 4-flat harnesses with a clip for the ground and loose ends with round push-on connectors.
I bought this at U-Haul a while back to tow a car hauler.
Again - 2 pieces, 7-round RV style with a 4-pin end on it, ( no cable, looks like an adapter) and the 4-pin harness with loose ends to the trailer wiring.
This should work for you.
