3. Connect the controller to ground.
Locate a suitable body ground to connect the black wire from the
controller’s main wiring harness. Existing body ground locations are acceptable as long as they are
clean and installing the controller will not compromise the existing wiring. A ring terminal has been
provided for installation convenience.
4. Connect to the pump.
Route the blue wire from the controller’s main wiring harness from within the
cabin to the injection pump (usually in the engine bay). Connect the blue wire to the pumps positive
(RED) wire. Connect the pumps negative wire to a body ground. Route the blue wire along side or
within existing wiring harnesses loom to reduce chance of abrasion or exposure to excessive heat. A
heat shrinkable butt connector and an additional ring terminal have been provided for this connection.
Replacing an Existing Electronic Pump Controller
Most controllers will have the same connections and may be changed out in minutes. Verify which
wires are power, ground, MAP and pump as different brands may use different color schemes. Retain
the inline fuse regardless of existing wiring configuration. If the existing controller does not have a
dedicated ground wire connecting to the sensor input this wire must be connected now. Refer to step 1
(above) for details on sensor wire taps.
NOTICE: Some competitor’s kits may ground the pump at the controller, instead of feeding it power. If this is
the case with your installation, ensure that the pump wiring is updated to reflect a positive feed from the
controller. This would involve connecting the pumps negative wire to the vehicles ground and the positive
wire to the controller as outlined in the above instructions. Additionally, if replacing a pressure switch
controlled system; ensure the BLUE wire from the controller feeds the pump directly, not through the
existing relay. If desired, a relay may be installed ahead of controller, but not after.
Now all the electrical connections should be complete and all equipment installed. If further clarification is
required, see the wiring diagram at the end of this manual or contact HPC at
.
Verify all connections are secure and that there are no leaks. Install fuse, if not already done, and reconnect
battery.
Test for correct operation.
Turn the ignition on, the pump should not be running. The POWER lamp should be illuminated and not
flashing. The ACTIVE lamp should not be lit. Warm up the vehicle and go for a drive. Adjust the knobs to the
desired set points and verify pump begins operation by watching for the blue ACTIVE indicator light. Once
the system is verified, tuning may begin.
Do not exceed speed limits and please observe safe driving practices while tuning.
If the pump runs when it is not expected to, fails to run, or the module indicates an error - consult the
troubleshooting section below.
