Question:

Question about a 2025 Chevy Equinox Activ hitch wiring. Currently, there is an installed trailer hitch and behind the hitch there is a plug that is terminated with jumper. From some searches, this is the wiring for a trailer and I seem to get conflicting information on the trailer site.

Hello Steven,

The great wiring fiasco of the 2025 Chevrolet Equinox.

We used to offer wiring that plugged into the connector you’re referencing to provide a 4-flat at the rear. Unfortunately, on models that did not come with the factory tow package, that plug is not active. We saw quite a few returns because of this. Chevy made the wiring system on these a bit too complex, and the aftermarket hasn’t fully caught up yet.

If you’re looking to add a 4-flat, you’ll need to splice in a powered converter like the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236. This installs by tapping into the vehicle’s tail light wiring (left turn, right turn, and running lights) and drawing power directly from the battery to properly power the trailer lights.

If you plan to tow a trailer with brakes, you’ll then build on top of the # C59236 by installing the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires # ETBC7. This kit adds a 7-way and includes the wiring needed to run a brake controller, including routing a power wire from the battery, a brake output wire to the rear, and a signal wire from the brake switch.

One important note during install: make sure the power wire for both setups is run directly to the vehicle’s start battery. Tying into another power source can cause inconsistent performance or damage to the converter.

What do you plan on using the wiring for, what are you towing?
