Is your ballast switch on the dash connected to anything? My 05 came with center ballast only which was controlled from the switch on the dash. I ordered parts from Skiers to add factory Gravity 3. It came with 3 rocker switches and a fuse/relay board that provides power to the fill pump when any of the fill switches are on. My switch on the dash isn't connected to anything now.
Also in your pic of the circuit board under the dash the power feed wire with the ring lug is not secured with a nut.
