GM hasn't changed anything ... Ozlander said "relay", not fuse. Yes, a new GM truck will often have a dummy plug in Stud #1 which one must replace with a fuse but this charge line circuit is not controlled by a relay as it is in Ford trucks.

Also, I think there is a relay you have to add.
I think all the info is in your owners manual.

Not in a GM, the charge line is hot all the time.

When did they change that? If has been nearly for ever than on GM products there is a dummy fuse in the underhood fuse panel that needs to be replaced with a real fuse.
But, if the OP has power like soundguy pointed out then the OP has a trailer wiring issue he needs to trace out.

My 7 Pin is not hot at my rear pin. The wire at the front by the battery is attached and I have checked my 40 fuse. I used a tester and the other pins have power but not the 12v power pin.

The wire should be under the fuse/relay box. It attaches to either pin 1 or pin 2. Others will tell which it is.
Added: Make sure the thirty amp fuse is a fuse and not a dummy one.
