No Power to 7-Way Plug?

When you say, “adding a fuse”, did you add an inline fuse or did you populate the fuse in the fuse box that powers up stud #1? Did you make sure there is power where you connected the wire?

Thanks for the reply! I populated the fuse in the fuse box to power stud #1, but I didn’t check if there was power to the wire. I’m not sure how to do that, but I did check the fuse with the multimeter and it was good. To check the power on the wire, would I take a voltage reading with the multimeter with the black probe on the truck frame and the red probe on the power wire while the truck is on??

Yes, but you don’t even need the truck on as stud #1 is on full time. You can also put the black probe on the negative battery post if it’s nearby (or use a piece of wire to get there).

I installed an automatic isolator (solid state) between the stud and the wire. Before that I would pull the fuse in camp so I didn’t run the truck down. You can unplug at the rear bumper easy enough. My truck also has an in-bed plug connected to the harness you mentioned that is stowed behind the cab. Both 7-way plugs are connected to the same place.
