What TM is best for M809 elecrical diagram

[70deuce]

What TM would have a decent electrical diagram in it? I'm pretty sure I have all of them for M809 series in digital format. Can't seem to find electrical diagrams. Also, Cummins coldstart glowplug, 12 volts or 24 volts at the plug? The tractor I am going to pick up has 24 volts at the glowplug and I think it should be 12?

My 1972 TM 9-2320-260-20 has many explicit diagrams...
