Review on 🚗 Enhance Your Towing Experience with CURT 56377 Vehicle-Side Custom Wiring Harness for Mazda CX-5 - Black [4-Pin Trailer] by William Kava

Revain doesn't show compatibility but I installed it on a 2021 CX-5 Carbon Edition. As already mentioned, the power supply is located on the passenger side in the cargo area. I used a 14-18 ga tap for the blue wire. It should be noted that most of the frame is painted on the inside, so be sure to get a solid base. I used an existing floor where the other two circuits ended on the driver's side in the cargo area, behind and under the gas cap. Check your connections with a multimeter once everything is hooked up, as detaching and reattaching the panels is a hassle.
