The
Haltech CAN Network
The Haltech CAN network allows for simple and effective expansion in ECU capability
and functionality without having to go to the trouble of wiring in a whole new computer.
Expansion is made possible by the addition of multiple expansion devices that
communicate to the main ECU via a Control Area Network (CAN).
Installation time and costs are kept to a minimum as all expansion devices are
powered up from the main ECU via the pre-terminated connection cable that comes
with each expansion device.
Simply connect the device directly to the 8 pin CAN connector on the rear of the ECU
or connect using an optional Haltech CAN Hub (order as part # HT0599910) if multiple
expansion devices are required).
Each expansion device is pre-programmed with a unique ID code which allows it to
be recognised on the network and work correctly first time every time.
For current available expansion devices please go to our website at

Remove the cover under the glove compartment by gently pulling it downwards
towards the floor. Your factory ECU connectors should now be visable. Proceed to
remove the glove compartment by un-screwing the two 8mm screws holding it in
place. Once un-done the glove compartment can be removed and the factory ECU
can be accessed.
