Or just use a multi meter. Turn your blinker on and see which one is going from 12vdc to 0vdc or so and so on.

tried the multimeter thing and found tail to ground, went to that to find ground wire, and when hooked up I found the light will work from one power to an unused power. tks, jds

I use hoppy's info all of the time. http://www.trailerwiring.com/inst/48485.pdf this is one for a 7 wire, but the color code is somewhat standardized.

I think what you are telling me to do is trace the wires from the trailer plug to the tail lights for the correct wire. I had not though of that but it might work because the trailer plug was not compromesed. I'll try it. MANY THANKS
