coin mech

This is sort of my last ditch effort to make the coin part of this machine work. Please see the photo below. I'm missing all the parts marked in red.

Hey All, I have recently purchased a Sega Naomi universal that was completely stripped of all original electrical wiring. I am attempting to rewire it and make it closer to the Japanese style candy cabinet. My question is i don't know the correct way to wire up the coin meter to get it to work...

I have the following coin mechs for sale: Qty 3 - ad81p 500Y Qty 1 - ad81p2 100y Qty 1 - ad81p3 100y Qty 1 - ad81p 100y Asking $20 plus shipping for each or $120 shipped for all 6. Thank you.
