Stacker removed code MK6

[Danos880]

I recently purchased a MK6, got a few of the door closed switches figured out and corrected.   Only issue left I believe preventing game mode is a "call attendant-stacker removed " code locking it up. 


Some wires have been spliced in, a cherry switch added for the cash door.  So there have been some modifications made more than likely while it was in service. I've tried manipulating the stacker micro switches.   No luck. 


So now from what I believe I read in the manual is when the stacker is removed it needs cleared through the operator mode.  I don't have the audit key yet but should be here in a few days from ebay.  Rather wait for it than trying to jump the switch.


My question is this the likely cause and likely solution to this code? I'm a little impatient waiting for the key, if I hear it will correct it I can wait the few days.  If someone thinks it won't help it's back to figuring out the wiring an switches.
