Quoted from ForceFlow:
It's kind of a pain to do on WPC games, but yes, it's possible. Just take plenty of photos of the connectors to make sure you don't get any of them mixed up.
If the connectors are factory original and not generic aftermarket housings with trifurcons the connectors will be individually keyed so that they can't be mixed up.
When you go to reattach them the wiring loom will also bend back to its original layout after 25 years locked in that position so the connectors will naturally come to resting in the correct general location on each board making it virtually plug in and move to the next one.
10 minutes to unplug and another 20 to replug them all back in once you get home.
Only other things will be the DMD ribbon cable alignment (red stripe for reference) and undo the wire from the grounding point nut.
Use this as your reference - it's all colour coded. I haven't bothered to mark them with the corresponding "J" number for years.
