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...

shows the center pin as Backup while the diagram above calls it AUX.
On the linked diagram, Yellow looks like what should have been connected (Called "reverse lights) to the Hot side of the LED, and its Ground wire should go to White/Ground. If it's LED, polarity matters. The light's ground should be on White.
If the LED is connected to the 7-way, make sure the wiring isn't damaged or loose.
Like RoyB said, most likely whatever color is to the Center Pin for the Hot, and Ground to White, Terminal #1, or any other good Ground.
Those pinch things are called Scotch-Locks.
