I've encountered a head-scratcher trying to wire some aux switches for my lockers and air compressor. I have some 5-pin rocker switches which allow the bottom half ("Front locker") to be illuminated when wired to another switched circuit. I tapped into Fuse slot #1 which I've discovered is the fuse for my instrument cluster backlights. After tapping into this slot, however, my rocker switch is ALWAYS illuminated, rather than switching to on when the multifunction stalk is turned and the dash lights illuminate. What am I missing here?
