Hi,

If it is an aftermarket box on the rear, the wiring may have been changed by the body company that installed it.

Take a look and let me know if they help.

Hi, so i got all the ground wires connected on the box, but after i started the truck, it shorted out under my dash, and i have some ground points that have come loose and blowing fuses. I'm not sure where they go.
that is possibly my issue?

Hi,

What shorted under the dash? Also, are you certain that the wires you refer to are all grounds? Could you take a few pics and upload them for me to see?

Let me know.
