Correct Trailer Wiring Harness For 2018 Mazda CX-5

Updated 03/06/2023 | Published 03/05/2023

Question:

I recently installed Tekonsha N118563 hitch wiring for a 2018 Mazda CX-5. At the power convertor, All of the wiring is tested as OK coming from the vehicle, including the power for the power converter, but once the power converter is installed, the 15A fuse for the system blows. The end of the trailer wiring isnt connected to anything. Any suggestions?

Thank you for your purchase from etrailer of 118563; the issue though is that this is the wrong harness for your 2018 Mazda CX-5, which is why it isn't working. The correct wiring harness for a 2018 Mazda CX-5 is the following:

- T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118746
