CONNECTING THE ESSENTIALS
(ELECTRONIC FUEL INJECTION)
Step 1: Ground
Splice the ground wires (Pins 15 & 16 Black)
from the Quick 4 into the main ECU (Engine
Control Unit) ground wire. Do NOT connect
the ground wires to sheet metal or other
ground sources. The Quick 4 MUST be
connected to the Main ECU ground, as close
to the ECU as possible. The reason for this
connection method is because the TPS is
shared between the two systems and
improper grounding will corrupt the TPS
signal.
Step 2: Power
Splice the power wire (Pin 9 Red with 7.5 Amp
fuse) from the Quick 4 into the main ECU
(Engine Control Unit) ignition-switched power
wire. Power should be supplied during
cranking as well as while running.
Step 3: Throttle Position Sensor
or Accelerator Pedal Position Sensor
Splice the Throttle Position Sensor signal wire
(Pin 3 Green) from the Quick 4 into the
Throttle Position Sensor (TPS) signal input of
the ECU (Engine Control Unit). If the vehicle
has Electronic Throttle Control, use the
Accelerator Pedal Position (APP) Sensor
instead of the TPS.
