coin mech

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.
