Okay boys, what did he do wrong?
So on this GMC K2500HD I bought the owner had a LED back up light installed, they used those things you put on the wires and then squeeze shut with pliers and it saves you time as it is quick, anyway...

Correct. YELLOW is the back Up light wire color. The Green(if standard tow wire colors are followed is the tailight signal wire). So, you are getting a feed back. The Ground on the Tow plug is the large white wire. Doug
