Taito Mystery Harness

Original wiring harness from an Taito arcade game. We aren't sure what game this is from, it has a 22 pin harness with a key pin at pin 20.  We do not believe it is from a Taito Classic Pinout game (Jungle Hunt, Elevator Action, Alpine Ski, etc). as the wiring doesn't correspond.  It does look to be from roughly the same era.  The monitor connector was cleanly cut off, looks to include wiring to the power supply, coin door and control panel from what we can tell as well.

The AC portion of the game wiring does not appear to be here. See picture for more details.
