Notice some cut wires on the solder side of the JAMMA harness:
Those gun connectors will run somewhere other than the JAMMA harness, so I wouldn't worry about them at all.Updated my previous post with pictures. Any advice on what I should buy/build to have an easily swappable control panel is much appreciated!
You're going to need to assess whether it's more worth your time/effort to replace those wires and add in new ones for buttons that don't exist on your cab (and make a kick harness), or to buy a pre-made JAMMA harness and adapt it to your current cabinet (and also make a kick harness). Either way you're going to need more wire, a crimper, pins, etc.
Either way you have a good amount of work ahead of you to re-purpose the cab.
