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...

I believe if you disconnect what's been done & determine which wire is hot & which ground for the light itself then connect the hot directly to the back-up light circuit you'll have better luck. Should be pretty easy.
