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

This wiring system is very easy to install! When installing I found that instead of connecting the black wire to the battery, it can be connected (welded) to a 12v socket in the trunk on the passenger side. This socket has a 15A fuse (the wiring system comes with a 10A fuse) so there shouldn't be any problems with that. This saves a ton of time as you don't have to run the black wire all the way to the front of the car! PS: I have a 2017 Mazda CX5 (Grand Select)
