It should be a #10 red wire that comes from the starter lug or the alt lug or a factory splice....... not sure how yours is wired.

In most cases the 10 gauge wire on the starter lug runs through a metal tube behind the exhaust manifold and up to the harness behind the valve covers. In this harness there is a Y connection. The wire on one side of the Y runs along the valve cover to the alternator BAT terminal, and the other wire runs over to a terminal junction mounted on the driver's side of the firewall. Power for the fuse box runs from this junction over to the fuse box.

The 10 gauge wire has a fusible link both on the starter end and on the end that connects to the firewall junction. If there has been a short, it often burns one of those fusible links. You can buy a fusible link replacement at just about any parts store - GM 14 Gauge fusible link (which protects a 10 gauge wire).

The fusable link is orange and should be 6-10 inches long spliced to the #10 red wire
