RT-622 Trailer Lighting

[oldguyinTX]

I am planning to install an LED light strip as a third brake like on my RT-622 trailer. There are three wires coming into the taillight assembly, 1 Orange, 1 White, and 1 Black. Does anyone out there know which color wire controls the brake lights, and which color is the neutral. If possible, I would rather not strip all three to find out which is which. Any help would be appreciated. Thanks a lot.

At the rear harness the following should be the code (standard Spyder color code).

Orange = running lights
White = brake lights
Black = ground

The colors may vary from harness to harness on the trailer and coming out of the taillight assembly itself, as well as on the old 9-pin harnesses, including the Spyder pigtail prior to 2013.
