Starter Signal (STS)
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

ECU Manager Software.
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
