Ok looking at your pic.....you have a standard 4 wire lead....white, brown, green, yellow.
White: ground, hook to all lights.
Brown: night time running, hook to the dim side of a dual bulb, or just to one set of your lights.
Green: right blinker/brake, hook to the bright side of a dual bulb(right), or just the right side of the other set of lights.
Yellow: left blinker/brake, hook to the bright side of a dual bulb(left), or just the left side of the other set of lights.
As to what pins on the deuce you hook to, I haven't looked that up.Clear as mud?
