Question:

Hey Mark. I checked with Curt and their item # C45FV is the correct wiring harness for a 2025 Mazda CX-50 Hybrid. This custom-fit T-connector plugs into your Mazda's wiring harness, which is located behind the tail lights. It will provide you with a 4-way connector to control your trailer or accessory's lighting functions.
What kind of trailer are you going to be pulling and do you already have a hitch? The Curt item # C33MJ is the only hitch available that works with the hybrid models of the 2025 Mazda CX-50.
