The wire highlighted in the photo is from a 72 wiring harness. It runs to the battery cable terminal on the starter solenoid. I do not know if it was originally wired in this location or if it was modified when the engine was rebuilt. It is currently serving the purpose of bringing 12V to an MSD relay that delivers 12V to the MSD HEI distributor. My question relates to the black rubber segment between the red wires with the two rubber blocks either side. What is it? The red wire is starting to fray where it enters the rubber block and I'm inclined to cut that section out and splice in new wire but wanted to understand the purpose of the black wire segment first.
Thanks in advance.

Thats a fusiable link, if the wire was to develop a direct short to ground (between the link and the starter), in theory the wire is to "blow out" and prevent a fire.
When these things "blow" the insulation usually stays intact and looking normal but feels like a straw because the wire inside burned away.

Super helpful, thank you!! That wire is fused higher up with an inline fuse carrier so the fusible link is likely redundant.
Can anyone explain what this wire segment is for?
