Question:

I have a 6 way, round connector on my rv. I have a 5 wire harness on my trailer with electric brakes. What apparatus do I need to connect the two?

I have an option for you, but you will need to make the adapter as there is not a 6-way round to 5-way adapter available, or change the connector on your trailer to 6-way round.

To make an adapter you will need the Pollak 6-Pole, Round Pin, Trailer Wiring Connector # PK11604 which will plug into the 6-way round connector in your trailer, then use the 5-Flat Vehicle End 5' Wiring Harness # HM37908 to connect to the 5-way connector on your trailer.

The other option is to cut off the 5-way connector on your trailer and install the # PK11604 that way you will not need to use an adapter.

I recommend using a circuit tester like # PTW2993 to confirm the functions of the wiring on your trailer, and wiring it following the included diagram of a 6-way round connector.

I included videos of the products mentioned and a link to a helpful article that goes over wiring for you to take a look at.
