Go get some labels to have on hand and a pen or marker.
Unplug any pins in the jones plug so it is empty. Lay aside your conductors with labels on them.
Start with the 1st unlabeled conductor and plug it into the "0" port.
With the playfield glass off and playfield up, start a game - to get it to go to ball 1 of course you have to close the outhole switch and then close the tunnel switch. Now run the score up until you hear the knocker go off. I see your kick-out holes score 200 points. Find a feature that will run the score up as fast as possible.
Your knocker should go off at one of these - 1,000,2,000, 3,000, etc., all the way up to 9,000. Mark the correct number on each unlabeled conductor and you're ready to go.
I see factory default high score replays for Spin a Card are 5900, 6500, 7100, and 7700.
Good game btw!
