Looking at the diagram below, yeah these are probably fusible links. Safe to say you cut the bad ones off and crimp the new on?
My wiring wasn't the same as this diagram. Differences are:
1. The diagram doesn't show the fusible link described by the first image above, for red. Again, this link is between the firewall block and where the wires are soldered as described above.
2. The diagram doesn't show the fusible link described by the second image above, for red. Again, this link is at the end of the red wire and attaches at the junction block.
3. The diagram appears to show a fusible link between the junction block and the positive terminal on the battery. Mine was just a wire.
Any input appreciated...........
