Auxiliary Output Connector
The Auxiliary Output connector contains two Digital Pulsed Outputs (DPO 3 & DPO 4),
and two +12V DC Switched power connections.
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
•
For a full list of output options and explanations please go to the help within the
ECU Manager Software.
