7-Way Round to 7-Way Flat Adapter Recommendation
Question:
Does this make the transition from a semi truck 7 pin round to the 7 pin flat RV trailer connector? The semi has different lighting. The brake and turn signal is similar to foreign cars that have an amber turn tail light and red stop lamp.

Expert Reply:
If your vehicle has a 7-way round connector like a Heavy-Duty, 7-Pole, Round Pin Trailer Wiring Socket # PK11720 then you could use a Trailer Connector Adapter # HM47425 to allow you to tow a trailer with a flat 7-way connector.
I also attached an FAQ article on wiring for you to check out also.
I would recommend you test the 7-way on your semi and determine if the 7-way has separate or combined tail light circuits. If you have separate circuits on the trailer connector you would need to wire in a tail light converter either on the trailer side of the circuit or the vehicle side. For a converter you would want a Vehicle to Vehicle Tail Light Converter # C56196.
