First and foremost, let's be safe about this. Please turn off and unplug your machine before installing the switch. When the machine is energized there are 43 volts DC present in the door at the lockout solenoid and 6 volts AC present at each of the lights. Thanks!

Now that we're safe, we need to open the door and remove the four phillips head screws that secure the front of the coin door to itself.

When the last screw comes out the front bezel should flop open like a well oiled machine! Right? No? Well, chances are if you have never opened this before it is full of nicotine and spilled beer/soda. This would probably be a great time to clean it! Otherwise, let's move on, shall we? On the front of the door, you will need to remove two more screws that hold the coin plates (or blank, if installed) in place.

Once the plates are out of the way, insert the credit button and plate in their place taking care to orient it according to the arrow on the back which should point up when installed and the front bezel is closed. Also, be sure to feed the wires through the bracket before securing it to the bezel with the same two screws.

Now feed the ends of the wires through the hole for the light. If there was a light installed there, you will need to either bend it out of the way or loosen the screw that holds it in place and move it to the side. Fold the bezel back into place on it's hinge and replace the four screws across the back.

The last step is to connect the wire ends to the credit switch the machine came with. You can use the alligator clips and simply clip it to the outermost tabs of any of the switches. You can also snip off the alligator clips and crimp on the included .250" connectors and slide them onto the tabs. (You may need to unsolder the diode and wires there for a good fit. Close the door. Plug it in and fire it up. Add some credits the easy way. Play some games. Play some more. Enjoy!
