How to Determine Reverse Light Wire to Install 5-Way
Question:
Could you help identify the reverse light wire colour on my 2020 XC90 to connect the 5th wire on this adaptor Thank you

Helpful Expert Reply:
The only way to determine which wire is the reverse wire on your XC90 is to have someone put the vehicle in reverse and for you to test the wires with the Cordless Circuit Tester # PTW2979. We simply wouldn't have any way of knowing specific wire functions on any given vehicle.
I have added a link below to a video install you may want to check out to give you an idea of how to install the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter # 20036.
