I created a little box, the Wife's old jewelry box actualy, with a lot of doorbell buttons in it. I then ran speaker wire from each button to whatever prop I was running. I had a mixture of pneumatic, wipermotor and Spirit Halloween props. for the Spirit props I kept the Try Me button on the prop and cut off the button, attaching speaker wire to the ends, then to the doorbell button. Not sure if I am getting the full use of the props keeping it in Try Me mode, but we too only activate certain props for certain TOT's.
