Controller Install
The progressive controller is NOT waterproof and should NOT be mounted in the engine bay!
Find a convenient location for the controller
inside the driver’s compartment. The adjustment
knobs should remain in an accessible location but still remain protected from possible water
incursion. 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. The controller contains
an externally accessible fuse, no additional fuses are required. Use the supplied zip-ties to
mount the controller.

pins 8 (white) and 9 (brown) may be connected to either of the two black sensor wires. The polarity is
unimportant.

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.
