*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.
External LED Install
Find a suitable location in the driver’s line of sight to mount the external LED. Mount the LED and run the wires
to the controller. The LED indicates the operation of the controller. If the pump is off and there are no errors, the
LED will be off. If there are no errors and the pump is on, the LED intensity will vary with the pump speed. If
there are any errors, they will be indicated by flashing the LED.
Boost Pressure Hose
Using the supplied vacuum tee and rubber hose, tap into a manifold pressure (vacuum/boost) line.
