7-Way and 4-Way Trailer Wiring Recommendation for 2019 GMC Denali


I have 2019 GMC Denali ruck I need the trailer socket connector that fits in the bumper The one on it now says GM 84056018 Do you have one that will plug in Thanks


Expert Reply:

The Hopkins 7-way and 4-way part # HM40975 that you referenced is the same as the GM trailer wiring adapter you mentioned. This will plug right into your factory wiring and will give you the same style of 4-way and 7-way you are looking for. It comes with a bracket that you just wouldn't need.
