Super repairman Trailer round

Buy on Amazon

Compared with other round in this category, the super repairman trailer round has a convenient design. It's nice to have two different pins, a 4 & 5 plug. It converts a round 7-pin connector to a standard 4-pin or 5-pin flat connector, so as to provide a solid power supply for towing most 4-pin and 5-pin kit. If you have a trailer with surge brakes it uses the reverse light signal to let you back up without locking brakes also.

This plug allows the use of both 4 pin and 5 pin trailer plugs, so serves double duty in a single unit. It’s a standard size adapter as long as your Denali has the round plug in. It's easy to install in seconds, so does removal if you don't need it, which is just as quick as unplug a connector. It is suitable for boat, rv, atv, chevrolet, ford, dodge, ram, toyota or gmc.

• Nice and easy for multiple connections
• Locks snugly into the outlet and confirmed all lights on the trailer works
• Good brand reputation
