This wiring harness will allow you to connect a 3" trackball unit to a 138/276/352/412-In-1 JAMMA board. The trackball harness has a block connector at one end which connects to the trackball input pins on a 138/276/352/412-In-1 JAMMA board and also has two plastic block connectors on the other end to connect to the x and y axis pins on 3" trackball units that have these.
Simple plug "n" play - once connected, the JAMMA board will detect the trackball automatically, so you can take control of games like Centipede and Millipede and play them as they were intended to be played with an arcade style trackball.
