When I have damaged connectors on that speaker I use the two pin connector from the belly switch (I bypass the switch) I add some wire onto the existing wires and install the connector on each side, speaker and the cabinet. after I install the coin tray I just plug it in. Works great, and I never have to worry about some one damaging the connector when they install the coin tray. you do have to remove the bracket and plug from the coin tray, and I usually remove the connector from the cabinet as well.
Hope this helps
Jim
