more pics.. check the 2nd pic... the game had the usual hard wired connectors on the power supply, so i had to cut them close to the power supply in order to remove the backbox.. well 2nd pic shows what i found when i looked closer at the wiring...

so you need to remove the backbox... simply cut the wiring loom in the MIDDLE  and solder it up later and NOT INSULATE the wires !!
