It is very easy to upgrade to a real knocker.
You need the latest firmware 1.0.3
a standard wpc knocker assy just check the part number from a AFMR manual
2 pin cable and a standard molex 2 pin connector
there are already the holes inside the cabinet.
info:
you are not able to test the knocker at the Testmenue, but it will knock during gameplay
set the fake knocker to OFF
here are some pics
