This isn't the first time that a wiring harness with an old "Jones" plug went missing during a restoration. I know there are countless spares somewhere out there that can be modified or repurposed to fit and fulfill another application. (Remaking one from scratch is not an option for me.) So now, I'm hoping to find or adapt a coin door wiring harness for a 1973 Gottlieb Jumping Jack. It has a 10-pin Jones plug with 9 conductors and is probably about 24" long. It connects the coin door to the inside cabinet at the fuse panel. But I'll appreciate any advice or ideas anyone can offer who's been through this before!

Thanks jrpinball. Sounds like you've wired a few machines! Originality is not an issue with this project, so your solution makes perfect sense. The coin door is currently void of all parts except two bulb sockets, and of course the schematic doesn't show any jones plugs. So it will involve some brain energy for me to figure out which color wires have to be routed from the empty connector and which ones need to be either joined together or left alone. The replay unit is jumpered.

Actually, Pinsider "guru" jrpinball explained that I really don't need a wiring harness, so I posted in the right place! Thanks anyway.

Correct. I meant that bulbs are resident just above the coin door and need connections same area. Door bell buttons are NEVER an option! Aagh!
