Sun Tach question

That is the tach I bought on ebay. I know very little about wiring and electrical items. Will this tach require some type of transmitter/sending unit, or is it a direct hook-up to the coil?

Thanks,
Patrick

direct hookup...
i wish they still labeled gauges that nicely...nowadays i cant seem to find the china connector....

So the "trigger" connection goes to the + side of the coil? The ign goes to the
ignition switch? And I know the hole is for a light bulb.. should be able to scrounge one of those pretty easy.

the ign switch is switched +
the trigger is the neg side of the coil...i think? (to the points)

Trigger is the negative side of the coil.

I think the older two piece ones that needed a transmitter only had a (+) and (-) on the back. Street Rodder did an article on older Sun tachs.

Good find on the Sun Industrial Tach, I have one that goes to 6,000 rpms, still works like new from 1977.
Did you get the chrome can it sits in?
Check the calibration of it after it's installed, I have seen many that needed readjusted.
