Ok, I got jrok's multi-williams board in the mail today along with the original defender harness I ordered. It's not quite what I expected. The harness doesn't match anything in my cab. Idk what it's suppose to go to. Do I need some other kind of wire or something? I know for a fact none of the plugs coming from the JAMMA harness will fit anywhere in my cab.

Anybody know what I need to do?!?

The harness:

The parts it's suppose to connect to:

The Jamma harness plugs onto the jrok board and all of those pigtails connect to the socket housings of your cabinets harness... I think jrok has them labeled "Sound", "CPU" etc. Did you unplug the big 18 pin connector from the power supply (as shown in pic)?
 
I dont see a single place where these will plug in, plus the video and the power connectors are only a few inches long.
 
Yep, its a cocktail. I'm trying to restore it. I couldn't find the original board set for sale, so I went ahead and bought jroks board (which I will eventually use in a Robotron cabinet and maybe later use for an actual multi-williams cab).

I guess I better look for the original harness somewhere.

That looks like your cab doesn't have an original harness in it. Also that adapter is for Defender upright cabinets only. The cocktail has a second set of controls for player 2 on the other side of the table.

If you're missing the original harness completely it's way easier to just put in a standard JAMMA wiring harness, a switching power supply and run the cab and run with that.
