Jamma credit switch help

[Spike]

i bought a pandora 3 jamma kit and i cant figure out how to wire up a credit switch. Ive got everything else wired up and working but this simple thing is driving me crazy. Any help would be great!

Coin for Player 1 is parts side pin 16. Take the wire from there on the JAMMA harness, the other from a ground pin, connect each of those to a button. Not sure what your setup's like, but that should do it.
