Example locations for CAN Bus wiring
Application Information
This information is provided only as a guide for location of CAN wiring in
various vehicles. Racelogic assume no responsibility for damage due to
incorrect wiring of this product.
CAN Bus is a widely used multiplex wiring system that has been adopted by
most vehicle manufacturers. Other multiplex systems do exist such as VAN
and J1850 but these are not compatible with CAN Bus.
Some newer vehicles have the CAN Bus wires available on the OBD-II
diagnostic connector. However, the majority of vehicle makes do not make the
CAN bus wiring available on this connector. In these cases, it will be
necessary to hard-wire the CAN interface to the vehicle CAN Bus. If in any
doubt about fitting please refer to a qualified vehicle electrician for advice.
