What color wire on this connector is the reverse light wire?

The UHaul hitch pros write: "The purple wire on part 47185 is most commonly attached to the vehicles reverse light."

i need information on how to install this product

–Mosi 3/26/2015 5:15:35 PM

After installing the mounting bracket to your desired location, simply plug the 47185 4-flat connector to the vehicles pre-wired 4-flat connector. Ground the 47185 white wire to a clean surface on the vehicles frame. These simple steps will power your trailer turn signals, brake lights and running lights.

You will then be left with 3 wires to attach if applicable:
Black wire - When properly installed the black wire charges the 12 volt trailer battery.
Blue wire - When properly installed the blue wire powers the trailers electric brakes.
Purple wire - The purple wire is typically attached to the vehicles reverse light for releasing a boat trailers lockout brakes.

For more information, please see the instruction sheet by clicking on the PDF at the top of this page labeled 'Installation Instructions' or visit your local U-Haul hitch center. Thank you!
