Many hours of tracing and cutting and crimping later, the second wiring harness is done!!! This means the original can go back in the cabinet.
It's assembled as far as it's gonna be for now. A friend tipped me off to gray wire tiedowns which appear to be exactly the same as the OEM ones used by lots of arcade manufacturers. They are by a company called Nix and the part numbers are UL-13G and UL-18G. After a lot of looking at reference photos, I think I was able to get the wire ties in the correct spots. Everything powered up and I could hear the game running, but considering the cabinet was working in the state it was sold to me that's not really surprising.
Previous owner hacked up an oddly short power cord to add a rope light so I fixed it with a proper gray cord of a decent length. I did change the power wiring a little bit so the rear power switch also cuts off the service outlet, which I know isn't factory, but I really don't like anything being live when the switch is off. I can also use this to add a subwoofer later, which I do in all my cabs.
New fixture was dirt cheap and illuminates everything nicely. Color temperature is too cold for my liking but I'm not in a hurry to replace it.
I've ordered caps for the factory power supply, buttons and sticks, as well as samples for the blue vinyl and the rubber mat. I did recap the chassis months ago but never tested it, so I did that just now and it powers up and everything works but the horizontal output is noisy, like the sync is bad even though it's not. I will have to look into it tomorrow.
