Ok guys this could be hard to explain bit I will try.

My 08 tournament team, the ballast pump switch has died in me. I got a new one which was told is the only one there is. The old switch (fill/drain) has 7 'prongs' and 7 wires. The new switch has 8 prongs. I can't get it to work or find a wiring diagram.

If its a Carling switch, the major difference between the 7 and the 8 pin is that pin #8 is a dedicated B+ for the switch illumination. #7 is the ground for the LED and the other 6 are the same.
