Is it just a loop of wire for the ALT terminal? You can replace it with a 100A fuseable link from your Toyota dealer- the kind with a clear plastic lid and visible element inside. It should bolt right in place of the wire. IIRC, you've gotta take the fuse panel out, turn it over and remove the screws that hold the ends of the wire in place, then just put the link in place of the wire.
HTH,
