Response from Jonathan: Since a 60-in-1 uses the JAMMA standard, you can use the JAMMA pinouts to locate the coin switch pins on the harness. You’ll notice from the pinouts that the coin switch wires are located on pin 16 (parts side) and T (solder side). All you need to do is run these wires up to the coin switches on your coin door along with one of the ground wires from the bottom of the harness (pins 27, 28, e, f). Wiring a coin switch is pretty similar to Wiring A Push Button so make sure you check out that post for some additional information. You can also hook the coin lights up as well by running the correct voltage wire (either 5 or 12 VDC depending on your bulbs) and a ground wire from your power supply to your coin door. You might also check out our video on Wiring An Arcade Cabinet Using The JAMMA Standard for more information. Hope that helps.
