In Cabin and DPO 3 Harness
The In Cabin and DPO 3 harnesses comprise of the following wire connections
• Digital Pulsed Outputs 1, 2, 3 & 4 ( V/B, V/BR, V/R, V/O )
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. 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
For a full list of output options and explanations please go to the help within the
ECU Manager Software.
• Digital Switched Input 1 ( GY/G )
Digital Switched inputs are inputs that toggle between two states of
low (0V) and high (5V) Voltage to describe the state of a switch or sensor.
These outputs can be programmed within the ECU Manager Software to control
auxiliaries such as:
• Air Conditioning Request
• Auxiliary Rev Limit
• Datalog Activation
• Launch Anti-Lag Switch
• Nitrous Enable
For a full list of input options and explanations please go to the help within the
ECU Manager Software.
