Expert Reply:
We can get your 2021 Buick Envision set up with a 7-way that also has a 4-flat so you can plug in either a 7-way or 4-way trailer connector. The first thing you will need is 4-way (if your '21 Envision does not already have one):
- With Factory Trailer Connector: Vehicle Wiring Harness # C56325
The 4-way is needed to activate your trailer's lighting functions, and it will then plug into the 7-way, and for that, along with the rest of the wiring for the install, you'll need the following kit:
- Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat # ETBC7
That would be everything you need, and allow you to plug in a 7-way or 4-way.
