Need a Vehicle 7-pin Round Adapter to Connect to a Boat Trailer 5-Pin Flat

Question:

Bought a pontoon boat with a 5 pin flat wiring connector. My van has a 7 pin round trailer receptacle. Can you recommend an adapter?

We do offer several adapters for a 5 pin flat to a 7-way blade vehicle connection. If your van connection point is a 7-blade configuration then you can use the Optronics # A75TB. This is an adapter that will plug into a vehicle 7-way blade style connector and will attach to your 5-pin flat boat trailer wiring connector.

If your van has a 7-way round pin vehicle connection pin, unfortunately we do not offer an adapter for that configuration. However, there is an option, and I recommend using the Hopkins Endurance Multi-Tow Connector # HM48470 to re-wire the connection point on your van to utilize a 7-blade configuration as opposed to a 7-round pin connection style.

I have provided links to the parts referenced above, a short video, and a helpful article that shows the typical trailer wiring configurations and functions for your reference.
