All good guesses, but... PIGS is the acronym for ‘Passenger Inward
Guidance Systems’, the moveable temporary barriers to guide passengers
safely to/from the aircraft on the ramp.

I agree with you both. “Pigtail” is a term I remember being used to refer to the end
ofelectrical connections – ground power supply cables, helmet leads, intercom leads etc . . .
, probably for the reason you describe, Moose.

I have a feeling, Mike, that a "pig" is a short electrical connection lead, to
connect, say, an amplifier to the power supply from a mobile generator on site. I don’t
know how I know that, since I do not recall ever working as a roadie at Glastonbury (other
venues are available) - but it might be consistent with an aircraft shore supply/intercom to the
flight deck.
I suspect the term comes from 'pigtail', which comes from pigtails in hair,
many strands braided together, then spreading separately at the end. More
generally, it seems to have been used for all sorts of short
electrical/electronic connectors that break out the individual strands.
From there it's easy to see it being applied to various short, multi strand
connectors. I see it is specifically used now for fiber optic cable breakouts,
at least according to Wikipedia.
Also, short, braided connectors in electric motors and generators.
So, I'm guessing you are right, and it's a shore to aircraft connector.
