How to Create an Adapter for a Vehicle's 6-Way Round to a Trailer's 5-Way Flat

Question:

I have a Winnebego 2003 that is wired for 6 round. I have a boat with a 5 flat plug. Do y’all sell an adapter that will make them work together?

We do have a way for you to connect your 6-way round and 5-way flat.

We don't have a direct adapter, but a combination of two with a bit of splicing will do the trick. First, use part # HM47415 to convert your 6-way round into a 6-way square. Then, remove the 6-square from that and attach part # HM47900 to give you the 5-way flat connection point. I've linked to a help article of wiring to help you with this along with video reviews of both of the adapters.

You won't be using the 12V wire, so I recommend removing that wire from the 6-way to keep it from drawing power.
