I have a 2003 Silverado 1500. I have a dump trailer. I just re-wired my dump trailer. When I plug the trailer into the truck I get crazy results on my trailer lights. I need to know on the truck side 7 pin what each color wire does. There are 7 colors, red, dark green, brown, yellow, blue, black, light green. So what I am looking for is: Red = right blinker blue = left blinker and so on.... Please help Thanks! Clark
