compared to the conditions of the other wires, I'd say the yellow was added more recently.
Can you follow it back to where it originates? The ring is not scored at all indicating it has never been connected.

I think kross is talking about the thing with the battery terminals and the heat sinks. Perhaps an inverter?

I believe OP is referring to the transformer / heat sink looking jobby with the 2 red and 1 orange wires affixed to the top of it. Then again...

It's a multi battery charge isolator. The charging source (usually an alternator) and the outer terminals usually go to batteries. It allows the charging system to charge two different batteries but keeps them separate so they cant draw off each other. It's two very large diodes encased with a heat sink.

It probably is the negative lead for a newer battery charger.

Look for the charger then look up the owner’s manual for it online.
