Question:
Hi I have a 2021 Chevrolet Traverse and I would like to know which to which wiring connection I need? Do you have a seven and four pin connection or only a seven or four then connection?

Hi Motty,
2021 Chevy Traverse's have a factory connector at the back to plug into so you can go with either a 4-pole # C56394 or 7-way # C56393 connector depending on your needs. Personally, I'd go with the 7-way and if you need to connect to a 4-pole trailer wire harness you can just use an adapter # PK12716. Having a 7-way will allow you to install a brake controller and tow trailers with brakes so it's just going to offer more versatility.
To mount the 7-way connector I recommend picking up the # 18140 and # PK12711U and attaching it to the crosstube of the trailer hitch.
