• This harness is ideal for  replacing old harness in any old JAMMA cabinet or for customers who are bulding new machines with JAMMA boards
• All  wiring uses 22AWG (22AWG is enough for Jamma PCB ) ,Cheaper harnesses will only use 24AWG or 26AWG or even (Marked with 22AWG but actually with 24 or 26 AWG quality ) The problem is if the resistance of wire is too high, it can cause a significant power loss before the DC voltages even reach the JAMMA PCB
• Fast connection to power supply with attached terminal forks for all voltages (+5VDC, +12VDC, -5VDC, GND)
• Video signals connect through included standard monitor connector
• Full Grounding Loop for all those joystick/button micro-switches on yourcontrol panel
