Harness Pinout 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-5 labeled connector is a spare Analogue Voltage Input (AVI-5).
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

ECU Manager Software.
