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 using the multimeter with the black probe on the truck frame and the red probe on the power wire stud while the truck is on??
