Power Supply Knowledge Help/ Street Figher II Champ Edition

New to KLOV and arcade hobby. Bought a Street Fighter II Champion Edition that had a rainbow bootleg PCB board and now I am converting it to the original 3 part board, kick and JAMMA harness. Looked in the back and I have no clue how and where everything should connect for power, monitor etc. I usually see a Suzo HAPP Power supply but this time its TWO Peter Chou type with hacked wiring. Not sure if it suppose to have two and I cant find any manuals with that info. My goal is to clean up all the wires to its original state and install the new JAMMA harness and get rid of all this mickey mouse mess. See attached photos. Any help will be greatly appreciated, Thanks!

a guide to the plugs on the power supply... the 9 pin plug (3 red +5, 3 black ground, yellow +12, white -5, and maybe blue too for -12V) is for the logic voltages that connect to the JAMMA harness. the 3 pin (black, green, white) is an AC accessory plug -- for some games this is either used for the monitor or marquee light. the monitor will either be a straight connection to the monitor power plug in the instance it doesn't need an isolation transformer, and in others it will wire to an isolation transformer's primary side, and the monitor's power will come out the secondary. there may also be a 4 pin plug, this goes to the cabinet's on/off switch if it has one. the power supply itself may have 1 or 2 power switches.

thus, the 9 pin plug goes to the JAMMA harness, the 3 pin plug goes to the isolation transformer, and the 4 pin plug will go to the cabinet on/off switch if necessary.

the reason they have 2 units in there is because the original large XT style power supply (probably with a hole in the side of the cabinet to access its on/off switch) died, and they rigged up the other smaller AT one in its place. the proper one you would need would be the larger one.

PM me for a part number from Suzo-Happ if you can tell me what your on/off switch is.
 
Cleaning up the Wiring Mess! SFIICE

Thank you all for your help. This is becoming much clearer and less scary. I have attached pics of the process. removed the control panel and board out of the way and gonna start fresh with new and properly wired power supply for this game. I am afraid of messing up the wires but my harness is labeled and shouldn't be so hard I hope. Thanks!
