Was changing starter and there are 2 8-10 gauge wires that come down back of firewall that appear to have been a fusible link. There's a lil black\round connector and it turns into a smaller wire that goes to solenoid. The smaller wire has rotted away,where can I get this? It looks like its gonna hafta be the something to reduce down to a smaller wire and how in the world is it possible to lay on your back and cut/splice wires and tape them up?
