You need a AE2631D5 or 7. The last number is the size of the bill box "5" is a 500 note bill box and a "7" is a 700 note bill box. You'll need to remove the display and mount it on the
door, relocate the controller to the back of the ACW, run a cable from the controller to the display and you should be in business. You want to be very careful when you plug the
Etowah valley relay box into the validator, plug it in backwards or one pin off and poof the smoke will come out of the validator and it will be ruined. I personally like the
Hamilton relay pan, it's almost impossible to plug it in backwards, it takes up the whole slot on the side of the validator.
