Quick hour meter wiring question

[AOW162435]

I want to add this hour meter to an older tractor I have. Based on the pics below, does anyone know which prong goes to (+), which goes to (-), and I guess the other is for ignition?

One lead will go to ground (-), another to switched (+), the third to ign (-) [Tach signal] As far as which one is which on the meter? I hope you have some documentation.

Eric,
Thanks. No documentation, hence the question.

After taking a look at the website, My guess was probably totally off on the hook-up. Good luck with that.....
