I recently purchased a 4-way trailer wiring harness from you all and I cannot figure out where to connect it on my 2021 Chevrolet Express Van without the tow package. Can you please help me out?

It does not matter which 4-way wiring harness you have. It can be the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part # 118392, the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part # 55540, or the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part # 31345. They all plug in to your vehicles lights at the same spot. Personally, I am a fan of the Tekonsha T-One wiring harness.

If you look at the rear of your 2021 Chevrolet Express Vann, on the left hand side, you will see some plastic trim. This trim needs to be removed. We do offer the Powerbuilt Trim Pad Remover, part # ALL648544, to help with the trim removal. Once the trim has been removed you will find the light where you will plug in the t-connector behind the UPPER panel. You will remove the existing connector, plug in the t-connector, and ground the wiring harness. It is easiest to attach it to the existing ground wire. You have to repeat on the other side of the van.

I have included product description links, video installation links, a review link, and a picture of the rear of the van showing the trim panel that needs to be removed on the driver's side below.
