Question:
I have a 2025 Buick Enclave Avenir. I want to use a tow dolly to tow it behind my Motor home. What wiring kit appropriate to power the vehicle turn signal and brake lights by the motor home? I am confused by your website. It shows a product but states it is Not confirmed to fit a 2025 Enclave.

Hi Ed; the Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles # RM-15267 isn't listed as a fit because the 2025 Buick Enclave cannot be flat towed. A dolly like the Roadmaster Tow Dolly # RM-2050-1 typically comes with a light kit so tow bar wiring is not required. However, the diode kit is universal so you can install it on your Enclave if you prefer to run your lights that way.
Where are you headed once you get the Enclave set up?

The wiring works great. Installed on 2023 Ford Ranger with no issues. I would recommend for sure.
