Question:

I purchased a T-One Vehicle Wiring Harness with 7-Way Trailer Connector Item # 118289 for my 2014 Acura MDX to use with electric brakes on a small camper. The hitch installed by U-Haul, Drawtite CQT75225, has a horizontal plate to mount the plug see photo, I am looking for a 7-pin and 4 pin connector. With this product 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket - Vehicle End Item # HM40975 connect to my Drawtite CQT75225, hitch? And will the cable adapter from T-One Vehicle Wiring Harness with 7-Way Trailer Connector Item # 118289 fit the back of the socket on this bracket see circled plug?

Expert Reply:

Yes, it will. The 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket item # HM40975 connects to the standard USCAR connector. A USCAR 7-way socket is a standardized automotive electrical socket that provides a connection point for trailer wiring so it will work perfectly with the T-One Vehicle Wiring Harness with 7-Way Trailer Connector item # 118289.

Please note that only one connector a 4-way or a 7-way can be used at a time because the covers on this socket will not open far enough to allow use of both plugs at the same time.
