A heavy gauge ground / earthing strap should be used to ground your engine to the
chassis of the vehicle. The Haltech Terminated Engine harness does not ground
your engine.
WARNING!
Damage can occur to your harness and / or ECU if you do not ground
your engine properly. Please ensure heavy gauge cable is used.
• Keep all wires away from the Exhaust manifold.
Termination Descriptions
Analogue Voltage Inputs (AVI-5, Fuel-P, Oil-P)
The Analogue Voltage Inputs can accept variable voltage inputs from 0V to 5V.
These inputs can also accept switch inputs that change between two different voltage
levels. The on voltage and off voltage define what the thresholds are between the on
and off states. The voltage can be viewed as a channel in the ECU Manager software
to determine thresholds for a switched input.
Fuel Pressure Sensor (Fuel-P)
The Fuel-P labeled connector connects directly to the fuel pressure sensor on the
engine. This will enable the user to know the current fuel pressure of the vehicle.
Oil Pressure Sensor (Oil-P)
The Oil-P labeled connector connects directly to the oil pressure sensor on the engine.
This will enable the user to know the current oil pressure of the vehicle.
Analogue Voltage Input 5 (AVI-5)
The AVI-2 labeled connector is a spare Analogue Voltage Input (AVI 2).
The 4 pin connector has the following terminations,
Please isolate all unused terminations.
Pin # 1 – Blk/Wht : Sensor Ground
Pin # 2 – Org : +5V Sensor Power
Pin # 3 – Org/Grn : Sensor Signal
Pin # 4 – Unpopulated
This input can be programmed within the ECU Manager Software to read inputs
such as:
• 02 Sensors
• Pressure Sensors
• Temperature Sensors
• Various Switches
• Trim Module
For a full list of input options and explanations please go to the help within the
Alternator (ALT)
The Alternator output connects directly to the OEM Alternator.
The +12V signal and alternator excite wires are pre-wired into the loom
Camshaft Position Sensor Input (CAM)
The Camshaft Position Sensor Input (CAM) connects directly to the OEM camshaft
position sensor located at the top of the engine block at the rear of the valley cover.
The camshaft position sensor is used in conjunction with the crank angle sensor to
determine crankshaft position and stoke of the engine.
Crank Angle Sensor (CRANK)
The Crank signal connects directly to the engine Crank Angle Sensor located in the
right rear of the engine block behind the starter motor.
The Haltech ECU uses this signal to accurately measure crankshaft position and engine
speed.
Engine Coolant Temperature Sensor (ECT)
The Engine Coolant Temperature Sensor input connects directly to the OEM engine
coolant temperature sensor located towards front of the head of the left bank.
The Engine Coolant Temperature Sensor provides the ECU with a signal that allows
the ECU to know the current engine temperature.
Ground (GND)
The Ground cable connects directly to the engine block.
Warning this in NOT the earth cable for the engine, please ensure that you earth your
engine with an earth strap from the block of the engine to the chassis of the car.
Damage to the ECU and or terminated harness may result if this is not done.
Ignition 1-8 (IGN1, IGN2, IGN3, IGN4, IGN5, IGN6, IGN7, IGN8)
The ignition outputs connect directly to the ignition coils.
Please ensure the correct ignition output is connected to the corresponding coil on
the engine. Please refer to the label on the harness for correct cylinder coil allocation.
Injection 1-8 (INJ1, INJ2, INJ3, INJ4, INJ5, INJ6, INJ7, INJ8)
The injector outputs connect directly to the injectors.
Please ensure the correct injector output is connected to the corresponding injector in
the engine. Please refer to the label on the harness for correct injector allocation.
Manifold Absolute Pressure Sensor (MAP)
The Manifold Absolute Pressure Sensor is located on the intake manifold.
Connect the MAP labeled connector directly to the sensor.
The MAP sensor measures changes in the intake manifold pressure which result from
engine load and RPM changes and converts these into a voltage output so the ECU
knows the manifold pressure.
Vehicle Speed Sensor Input (VSS-Input) (optional)
The VSS-Input does not support the OEM reluctor style sensor.
Provisions have been made to allow the user to connect a supported Hall effect style
vehicle speed sensor.
The sensor provides information on vehicle speed to the Haltech ECU which can be
used to display vehicle speed, detect gears or controlling of switches etc.
Connect a supported Hall style sensor as follows.
Pin# 1: Blk/Wht – Sensor Ground
Pin# 2: Gry/Red - +12V Sensor Power
Pin# 3: Grey (Shielded) – Sensor Signal

The Starter Signal connects directly to the starter motor solenoid.
This will supply 12V to the solenoid on receiving a start signal from the ignition switch
when in the start position.
Please ensure you supply a main power connection to the starter motor and a
main earth strap to the engine to ensure correct operation of the starter motor,
and to avoid damage to your terminated harness and ECU.
Spare Digital Pulsed Output (DPO-4)
The Spare DPO connector contains one Digital Pulsed Outputs (DPO 9),
and one +12V DC Switched Power.
When the output is activated by the ECU the output will switch to ground.
Solenoid valves and shift lights etc can be run directly from the output, however high
current devices such as thermo fans and additional fuel pumps must be activated
through a relay. A Relay can be wired between the DPO and the supplied +12V DC on
this connector. This way the output is only switching the relay and not a high current
draw device.
The Digital Pulsed Outputs are limited to 800mA Max current draw.
These outputs can be programmed within the ECU Manager Software to control
auxiliaries such as:
• Air Con Output
• Aux Fuel Pump
• Boost Control
• ECU Diagnostic Light
• Intercooler Fan
• Shift Light
• Thermo fans
• Reverse Lockout Solenoid Valve
For a full list of output options and explanations please go to the help within the
ECU Manager Software.
Wideband 02 Inputs (02-1 , 02-2)
