Larson Electronics Trailer Plug Adapter - Female 7-Pin Round to Male 4-Pin Flat Adapter

The TPH-7RF-4FM from Larson Electronics is a trailer plug adapter. This adapter goes from a female 7-pin round plug (with round pins) to a 4-pin flat male plug. This allows operators to plug in 7-pin round plugs from lights, trailers, or equipment into this adaptor, which will convert it over to a 4-pin flat to plug into the female receptacle on the tow vehicle.
