4-Way Trailer Wiring Harness for Mazda CX-5  

Published 08/10/2026

Question:

@JamesonC My Mazda CX-5 is not going to tow or operate a trailer with brakes. I only bought this custom harness so I wouldn't have to cut into my stock wire harness. I'm only going to be operating trailer lights, turn signals , brake lights, flashers, etc with a four pin connector.

Hey John, the Curt trailer wiring harness part # C45FV is designed to provide the taillight functions you mentioned for your trailer's wiring so it would be exactly what you are looking for. What trailer are you towing and what year is your CX-5?

I think it's a 2023. The trailer wiring harness kit should indicate the year. I'll be towing a 14 ft aluminum boat with a 15 horsepower outboard motor.

@John This harness does fit the 2023 model like you have. It fits 2023 - 2028 Mazda CX-50 so far actually.
