I don’t know how you could have crossed the wires for the altenator, there is a cable with an eyelet and a field control connector that plugs in. Fuse #4 in the power distribution center (under the hood) only powers the fuel pump relay/fuel pump. If the fuse is blowing the fuel pump is likely the problem. You could first try exchanging the relay with another in the PDC. ---

You may have melted the insulation on a wire causing a short. Also, reversing the polarity usually burns several of the fusible links.
