Towing vehicle has round RV style plug-in and the trailer has a 7 pin connector — how do you make/find an adapter to make the connection. Thank you.

Helpful Expert Reply:

Though replacing the plug on your trailer with something like the Hopkins 7-Way RV Style Connector with Molded Cable - Trailer End - 8' Long - RV Standard # H20046 will be my recommendation, if you wanted to keep your current 7 Pin on the trailer, the following can be used to adapt it.

The Hopkins # H20046 will still be used, but it would be wired into the Pollak Bracket for Single-Pole Trailer Wiring Socket # PK11720. The 7-Pole Rubber Socket Boot # PK11761 would then keep the connections covered.

The # PK11720 can then be mounted on the Pollak Bracket for Single-Pole Trailer Wiring Socket # PK11771. From here, everything can be mounted to the Curt No-Drill Bracket for 6-Way or 7-Way Round Trailer Connector Mounting Bracket # C57202, but you will most likely need a longer hose clamp to secure to the frame of your trailer. With this using said hose clamp to attach, this can be easily removed when not in use as well.
