The Chevy Vega had side terminals in 1976. There was DARN little

the alternator was not producing, a timer on the rear window
defroster,
probably a VERY simple electronic ignition (I don't remember points
on that
one) and the radio. I don't think it even had intermittent wipers.
That
was it, and it was all analog stuff.

The fuel injection computer was for the 76 Seville. Since I worked for
a supplier of production test stations I saw developmental items
before they reached consumers.

It sounds as if you had a really fun job.
