All the wires and crimp-ends for the reload buttons and triggers were gathered. Each component used a different size of crimp end. The triggers, automotive switches, used 1/4" (6.3mm) quick disconnect ends while the reload button, arcade buttons, used 0.11" (2.8mm) crimp terminals.


All the wires were stripped at both ends. One end would be placed under the screw terminals of the control boards while the other end was given a crimp end. The thin metal didn't work with my crimping tool so additional compression was needed to hold the wire in place. Green wires were used for the reload button and black wires were used for the trigger. Since these were not polarity specific, no mindfulness was given to how each wire would be used on the hardware.
