Tinware writing, Was this on all cars…?? Options

Hi All

Have seen this on an unrestored car…does anybody have anymore details…? I assume the 022 refers to the 1.7L but what about the other number?

Any insight would be appreciated…thanks

Andy

Wonki...Your research is exhaustive, appreciated and commendable. I need to wade through this in greater detail althought I have been distantly keeping tabs on it all along.

But one thing piques my interest...you identify 4 engine tin codes which are really two sets of two codes that you suggest indicate both with/without the center console and gauges as a prime variable. The EC-A and EC-B designations appear on the emissions sticker so obviously they pertain to emisions in some way. And I like your throttle body/vaccum line arrangement discoveries.

But the center console with its gauges was an optional equipment item that is plug N play and has nothing to do with emissions. All 1974 914s had the same chassis harness with the center console connections in the cabin floor, whether the car was equipped with the console or not. Seems odd that the optional console would be somehow related to the engine tin code.

Your thoughts?

Unless (?) the tins for the console/gauges cars were just a bit different, like an extra hole or slit for sensor/sender wires to the gauges. Thoughts?
