Replacing Factory 7-Way on 2010 GMC Sierra with a 7- and 4-Way Trailer Connector  


I own a 2010 GMC Serria 2500 HD. I am looking at installing a lit hitch cover, and I am wondering it there is any way to disconnected the factory 7 pin adaptor from the female end and add an adaptor that will allow a CR-007 connection to plug into? I have found 7-pin to 4-pin adapters, but will require an extension, and a ugly adaptor pluged into the seven pin all the time.

Yes, you can replace the factory 7-Way only on your 2010 GMC Sierra with a 7- and 4-Way connector. You will need # HM40975. It also includes a mounting bracket and hardware since it will not fit in the same place as the factory connector.
