Hey, I just got your pm last night. My King Rock is in my storage unit right now, I think I have a schematic too. I'll bring my camera with me and go take a look at it this morning. From the picture above it looks like a yellow and green wire and a blue wire, I'll take some pictures and see what I can find.

From the picture above, it doesn't look like there are any leaf switches behind your stepper unit. I don't have my machine with me, but I pulled off my stepper unit and have that with me. The two wires in your picture above (top right and 3rd down on the left) both go to the two leaf switches behind the bakelite board. I'd be happy to take some pictures and get be more descriptive if it helps.

Your stepper unit is slightly different from mine, like a mirror image of it. Mine has A-8933 printed on it, yours is A-8934, but it's the same layout so it should work.

Here are some closeups of the switches and cams, I took out the arm and spring that does the ratcheting so that you could see the cams and switches better.

Here are the wires attached to the switches, the blue wire on top goes to the solenoid. The two cut wires on your machine go to the left switch on each stack in this picture.
