Hey Don! If you don't already have a 4-way that is where you need to start. You can add a 4-way using the Curt T-Connector Vehicle Wiring Harness # 55540. Once that is installed you will upgrade it to a 7-way using the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat # ETBC7. This kit comes with the adapter, wiring, and everything else you need to add a 7-way.

For a brake controller, I recommend the Redarc Tow-Pro Liberty # RED52VR. The Liberty is simple, reliable, and won't take up extra space in the cab of your van. The main unit installs behind the dash so only the control knob will be visible. The knob adjusts the braking power and acts as the manual override.

I went ahead and attached some installation videos below for your reference. If you have any other questions feel free to reach out in the comments.

Hey Don, did the installation of the 7-way kit and the Tekonsha P3 brake controller go smoothly on your van? I’m curious to know how it worked out for you because it could help others looking to set up their van for towing.

Answer 1

The Redarc Tow-Pro Liberty Brake Controller #RED52VR will work just fine for your 2017 Chevy Express Van. You'll just need to splice the wiring from the controller to the following functions: Blue - 7-Way Output to Trailer Black - 12V Power White…

Unfortunately that 12 pin rectangular plug has nothing to do with the trailer wiring harness. To add a 7-way and 4-way connector to your 2023 Chevy Express Cargo van you're going to need to buy two separate harnesses. The reason for this is that…

Answer 6

If your 2019 Chevy Express Van 3500 has the tow package there will be a round connector taped behind the rear bumper that a 7-way like the part #A10-7072VP could attach to. Otherwise you'd need to install a 4-way first like the part #118392.

Answer 9

Hey Joseph, since your 2022 GMC Van doesn't have the 7-way wiring that would indicate it doesn't have the factory tow package so you'd need to go a different route to install a 7-way. You'd need to first start with the 4-way kit part…
