What voltage you get from the voltmeter on the instrument cluster?
Cold start you should get 14v or a hair above. When driving and afer warmed up, you should have 13.5v to 14v at all times even with low beam and a/c on.

Question...
If I did have this cable problem, which I think I do on my '99 C2 which is now 17 years old and showing the symptoms, would it affect my idling?
I'm thinking maybe since my battery is not always at full strength due to not being charged properly during long trips due to the cable getting hot, it may be causing this annoying intermittent idle issue I can't seems to correct.
The idle issue usually appears when car is fully warmed.
Battery is new, MAF is new, idle air control valve replaced, no apparent vacuum leaks (was tested), oil filler tube not leaking, new oil cap, etc. Done just about everything to try and fix the idle.
Thoughts?

Thanks! The sunset link shows it as just the bare cable itself with no #13 - that plastic box. Can you confirm if it comes with it?

When you replace it make sure the cable is attached to the starter at exactly the same angle in which you removed it!
Mine was at a 7 o'clock position instead of 9 o'clock and would short the starter when I hooked the battery back up.

To my knowledge, no. Some think the -03 is updated, but I pulled a totally rotted -03 cable from my car. California/Texas car with under 70k miles at the time. If there's a difference, it sure didn't look like it.

Isla: Perhaps a previous owner replaced that cable and ended up installing a -03.
In my case, I replaced both Y-cable and battery (6+ yrs) in Dec 15 due to high engine-start impedance when the engine was hot. Engine would always catch and start but it was labouring and becoming iffy.
High impedance never caused idling issue though as a previous poster queried.
