Converting From 7-Way Round to 7-Way Flat Connector
Question:
I would like to tow and charge my dump trailer with an ag tractor. I would like to find an adapter to go from 7 round ag to 7 flat rv.

We do offer the Trailer Connector Adapter, # HM47425, which converts a 7-pole round connector to a 7-pole flat connector. This adapter works for tow vehicles with combined taillight wiring, meaning that the turn signals and brake lights run on the same pin.
If by chance your tractor has separate taillight wiring, meaning that the turn signals and brake lights run on separate pins, you will need to add a converter, like the Curt # C56175. Just cut off the 4-way end and wire it into this adapter. I have attached a picture which illustrates this.
In order to determine if your tractor has separate or combined wiring, I recommend using a circuit tester like part # PTW2993, to test the functions of each pin. When doing so you will also want to make sure that the connector on the tractor and the adapter are pinned alike. I have attached a picture for this as well.
