NEED HELP! VK tacho wiring?

[FreshLad]

I've taken a tacho gauge out of a old wreck 202 vk belina, to put in my executive. But dont have a clue what is suppose to come off the 3 little screws behind the tacho? does any one know lol

You also need the board behind the gauges, then it'll plug right in and work. 3 pins are +,- and signal.
