Autometer tach wiring?

[DemonDave]

I got a nice Autometer Sport-Comp tach from a friend today but have no idea which wire gets connected to where. Anyone have a wiring diagram for a tach handy?

Thanks!

A quick seach on summit found these Autometer tach instructions.

If you can find the exact one on summit, they should have a link to the instructions listed. Very handy when looking at parts to buy.
