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.
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

Connection Rules of the Haltech CAN Hub Mini
• The Haltech ECU must be in position 1 of the CAN Hub Mini.
• If only one device is connected, a Black / Black cable is required.
• The RacePak IQ-3 must be in the last position occupied on the CAN Hub Mini
that is furthest away from the ECU.
• The first and last positions occupied on the CAN Hub Mini must be terminated. This is
indicated by the use of a Black / Black cable. All other devices must not be terminated,
indicated by the use of a White / White cable.
• Positions on the CAN bus must be used in sequential order, (ie 1-2-3) Any break in the
position order will break the network.
• The total current limit on the ECU is 1A. Excessive current draw will reset the ECU's
internal fuse.
