Have you taken the instructions out of the bottom of the box and looked at them yet?

 

I can see it under the wiring loom.

This is a poor pic due to sun light but it's of the one on passenger side. Same on Drivers side. The wire appears to go to rear of the bed but I'm not sure where it connects.

It weaves it's way down through the holes in the tail light "pockets" and connects under the bed close to the spare tire and rear bumper.

Yes it says some accessories may require vehicle programing to complete installation and the instructions for this part are available  through GM service3 manual under the accessories manual.

So no help at all with the instructions.

I know the parts department can get you a set where you bought it from.

 

Or this might help:
