Thanks for reaching out!
The correct wiring harness for flat towing your 2023 Chevy Equinox Premier will be the Smart Diode kit from Roadmaster. You need part # RM26FR if you have incandescent tail lights or part # RM38FR if you have LED tail lights.
To determine the correct wires to splice into you need to remove the clip from the tail light and then use a circuit tester like part # PTW2992 to check what functions are on each pin. Unfortunately we don't have a pin-out of what functions are on what wire as of yet (since we haven't installed one on a 2023 Equinox as of December 2022) so you'll have to test it on your end.
Attached is an installation video of this diode system on a 2020 Equinox for you to check out. If you jump to the 13:28 minute mark you'll see the process of connecting the wiring.
