Aside from photo any idiot guide to do this?
Depends on what type of connections your encoder uses.
Screw terminals like an I-Pac:
- Run a separate wire from the Normally Open (NO) tab on each microswitch to the coin input -- two wires into one screw terminal.
or- Make a custom daisy-chain (shown in diagram above) for the coin input -- like a daisy-chain ground, but longer.

--------------
Prefab harness with quick disconnects (QDs) like the Mini-Pac or Xin-Mo:
- Make a Y-cable with 1 male and 2 female QDs -- female QDs go to NO on each microswitch, male goes to the prefab harness.
