Install Video for Installing 4-Way to 5-Way Adapter 20036


I am looking to purchase the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter Item # 20036 to be installed on a 2021 Mazda CX-9. Is there a video or documentation on where and what color the backup light is for the vehicle?


Expert Reply:

We don't have an install video for the # 20036 on a Mazda CX-9 like what you have. The process is the same for all vehicles though as it's a matter of testing the wires that lead to the reverse lights and tapping into the circuit that has power when the reverse lights are on. I attached an install video on a similar vehicle for you to check out as well.
