Sorry, not sure what the fuseable link is. Is this the wire lead that attaches to the starter selenoid and feeds all the other wires up on the firewall? The wire that looks toasty is attached to that lead appears to attach to several other wires that connect to a block with three connections attached to the firewall behind the dizzy. The melted spot is where I have this lead going in and multiple wires coming out. Everything north of that spot looks untouched. Do you think I can I avoid a full engine harness replacement?
