I have something similar to this in mine. It was mounted where the left price plate was supposed to be. I moved it from there, mounted it on a piece of metal and screwed it to one of those little rails stapled to the bottom of the cabinet inside the coin door. Then I set the switch to give 5 plays for every time I press it. Also removed the key lock and put in one of those little knobs that make opening the door possible w/o a key. Lastly, I fixed the open space in the coin door where the switch was with a new light and price plate.
This is a fun machine to work on. I am awaiting a play field protector once the place I am speaking to adds it to his inventory - I have a number of dished inserts.
