My truck is a V8 two wheel drive automatic with 85,000 miles. I need a diagram for the fuse box. The cover is missing along with the diagram. There are no fuses in the box. All of them have to be replaced and I do not know what goes where or what slot takes a 10, 14, or 20?
Do you
have the same problem?

In the main fuse box under the hood, check them all with a test light. If that fuse keeps blowing, suspect a shorted fuel pump

My circut for my tail lights has got hot at some point and melted the plastic around the metal female receptor for the fuse. Can I buy the female receptors and just use one of the open spots on the fuse block? If so where can I buy them

The dealers have replacement terminals for all of their connectors, but I'm not sure if that includes fuse box terminals. You can visit a pick-your-own-parts salvage yard and pop some terminals out of a similar fuse box. Some of the terminals will have a wire attached, but some are just molded as part of a string connected with a brass bar. Those bars can be soldered to, so you can run a short wire from your new terminal to the bar the old terminal was attached to. There are also aftermarket crimp-on terminals. You can slide the plastic cover off and solder those on. The drawback is those won't have the little finger that holds them in the slot.

As a less-attractive alternative, you can solder in a new fuse holder with pigtail wires.
