*Note: If fluid tank is equipped with previous generation level sensor, identified by having two black wires, then
pins 8 (white) and 9 (brown) may be connected to either of the two black sensor wires. The polarity is
unimportant.
**Note: If you need to extend the wires to mount the controller use at least 16 AWG wire for the pump and
controller ground circuits and 18 AWG for the remainder.
***Note: The external signal is only available for the Multi-Input Controllers. The Internal MAP, HD controllers will
not have this pin populated.
