Cold start glow plug light usage.
My light glows different lengths based on engine temp. Stays on almost no time if the engine is warm....stays on a really long time if its below freezing and I didn't plug my block heater in.
Is the light tied into the glow plug relay? There would have to be something that tells it to light up for a certain amount of time. It could be as simple as whether the thermostat in the coolant is open or closed...to a complete seperate engine temp sensor.
You guys talk about "those who understand it". I would like to join that club.

Botched is a very good word to describe the wiring of this car when I got it. I have since made it worse...and now...it is only slightly less worse than when I got it. But from even worse to less worse is an improvement. But I think the ground is fine. I get 14 volts at idle after I have been going a while. Fully charged battery + warm engine + low load.
