My pack is not a styrene or fiberglass shell, It was built with individual parts and boxes and wood. The sound does not come from a board, it is sequenced into individual speakers by individual separate sound chips.. For this light kit the main power needs to remain on for the barograph power down sequence and so the on and off (open closed) needs to run separately from the power. The main toggle switch power on on the gun box triggers power on to the relay to the already powered light board. The shut of opens the relay and lets the powered light board run its shut down sequence. It is the way I built it. Crazy but there you go.
