7 Pin Electrical Plug for Towing

[cdunclife]

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!

Near the letters are Red, Brn, Lt Grn, Dk Grn, Yel, Dk Blu, and Wht.
