BTW - one of the things on my (lengthy) to-do list is to see if a Ford voltage regulator will work with a Dodge alternator. (Yes, I'm an unrepentant heretic.)
I want both gauges and indicator (warning) lights in MLP for oil pressure, engine temperature, and electrical system. How to do that is already established for oil pressure and installation/modification shouldn't take more than two hours. (With most of the two hours spent looking for tools and supplies.)
Ford voltage regulators have a terminal specifically for an 'ALT' indicator light. If the Ford regulator and Dodge alternator will cooperate, that's solved as well. (Voltmeter rather than ammeter ... I've repeatedly expressed my disdain for ammeters in motor vehicles.)
All that remains is engine (coolant) temperature. Need to dig back in history to see how 'TEMP' indicator lights worked way back when, if they existed. (It's far enough back that people may have simply relied on steam spewing out of the radiator to indicate overheating.)
