you dont want to go down that rabbit hole. I have a freind who owns an old 1FZ-FE land cruiser (called gas sink)
he has 2 different coolant temp gauges (one front and one at rear of cyl head), AT oil temperature gauge, 3 diff oil temp gauges, engine oil pressure and temp gauges,
Sitting in his truck is like sitting in an oldschool ship bridge where you have analog gauges looking at you from all angles.
