I recently upgraded my dash with new switches. I am having trouble figuring out the bildge switches. I have a mid bildge and aft bildge. Both have float switches. The switch on the dash has "on" "off" "auto" positions. There is a small led light on the panel on each side of the switch to indicate when it is pumping; yellow led on the left for "on", red led on the right for "auto". On the back of the each switch is 6 tabs and two wires for each led light. I only have two brown wires for each switch from the bus bar. How do I wire these switches?
