I've been making/selling full replica MB harnesses (and individual pieces like CP harnesses) for years. Send me a PM with what you're looking for and I'll get it done for you.
I have (or can still make) replica dedicated PCBs and harnesses used in MP: Main PCB, Spinner interface PCB, power supply, filter board and sound board. Check some of my older posts and you can see all of them or PM for more details.
Most people wind up buying one of my all brand new Qbert harnesses these days. I still make them to order. PM me if interested. Here's an old thread with the details/pics:

Might be helpful to post if you need the upright version or the table version (aka Red Tent). I still make full replica harnesses for most Nintendo arcade games so shoot me a PM if you're interested for details.
Qbert and Three Stooges are very different harnesses -- different power supply and sound board pinouts between those two games (even though the PCBs are the same). I routinely make just about all Gottlieb video game harnesses, so if you want a brand new replica, send me a PM.
Funny you say that...I now have all 4 of those items reproduced.
Harness is completely different that the other Gottlieb games (it doesn't use a filter board).
I even made replicas of the sound boards (but I'm low on SC-01 chips) so I can provide all of it minus that chip.
FYI. The stock harness will be the same no matter what sound amp voltage you wind up needing. The important part is to match/pair the correct power supply with the correct sound amp on the sound board. Also, odds are very likely that you need the 30V style amp since I’ve never seen a stock MP...
I have made a few runs of these and they sold out immediately. PM me if interested and maybe I’ll run off a few more.
