Would a Boat Trailer Have a 7-Way Harness with only 5 Wires Ran to it

Question:

I have a 22 foot boat trailer. The wiring harness is round and looks like the 7 prong, but only has 5 wires. It broke and the wires inside are corroded. I am trying to find the wiring harness for the trailer approx 3 feet long but 5 wire round ? Is it possible or can th 7 prong be used? Also prob will replace the junction box.... Thanks

It is very possible that your trailer has a 7-way harness installed on it and not all of the circuits are completed.

For a 7-way and lead that is 4 feet long you would want the part # H20043. Then for a new junction box we have the # 38656. I attached an install video for you to check out as well.
