Looking at notes here, that's what was tried (in response to that vehicle wiring concern) here, however, no R3 was used (said another way R3 = infinity). Maybe time to revisit the concept once again, and see if a voltage as close to emitter voltage at Q2 (12.8V) can be had. Me seems to not do well calculating current flows and of course, there are gain variations between transistors to boot. On the flipside, there are several transistors in inventory here, and some extra 50K and 200K pot. Also have a 2K pot. Thoughts?

And if successful (initial test should answer a lot), proceed to mess with the 90% of the design that works perfectly. (?)

Thanks Duncan, it's always appreciated. Don't knock yourself out if you don't know, the direction/suggestions/concepts, maybe something I haven't thought about due to ignorance, it's all good.
