If nothing to add ie a marine, industrial type engine it does not ring a bell or jar the memory - I would say non OEM.

I am old. Been a mechanic for a long time. I have seen a few of those back in the day. Maybe I used to know what they were for. Now I can only guess that it is a spark sensor for add-on tach, cruise, etc.

Yep! I found this tag on the wire to the thing. We have a winner! I knew what it was and what it did, I just needed to figure out WHY it was doing it. Heh heh!

It may have been there to help keep the Cruise from Flooring the Throttle if the Transmission came Out of Gear.
