Wiring exists in the factory harness, but WMS did not install the knocker to save $$. The drive transistor for the knocker is still available even - just install it and play!
You can turn the fake 'knocker' noise off in adjustments.
Note the 2 sets of holes, I used a template I made from a T2 head and the knocker wasn't loud enough. Looked at my MM and AFM, and the solenoid appears to be closer in these games - so I measured and moved it up.
Will fill the extra holes and touch them up when I restore the machine.
