To add a 7-Way and 4-Way connector to your 2022 GMC Acadia I recommend the following parts:

T-One Wiring Harness - # 118276
Hopkins Trailer Connector Socket - # HM40975

The T-One plugs into OEM connectors at the back of your vehicle and then the Hopkins will install on the US Car connection at the end of the T-One. If you're also planning to install the Draw-Tite Trailer Hitch # 76023 the Hopkins mounting bracket will install directly to that mounting bracket on the hitch.

To complete your towing setup you're going to need either a ball mount or a weight distribution system. A standard ball mount is for lighter trailers while a weight distribution system is needed if your trailer weighs at least half the weight of your Acadia.

Let me know which one you're needing and what the weight of your trailer is and I can make a recommendation for you!
