Control wiring
feed and load common to one side of pot (left side if looking face on)
feed hot to other side of pot
load hot to center of pot
Can't/won't be adding amps, transformers or flashing LED disco lights. Volume controls are already present in each room. This worked years ago, it should work again. Just need to know how to connect what's already there, thank you.
