Race Technology CAN connections

CAN connection cables can be found in different places: behind the instrument cluster, near the steering column, behind the fuse box or the glove box inside the main wiring loom. Regardless of the stock ECU installed on the car, colours of the cables you need to connect to are always the same, they are twisted and you can see them here below.

 CAN low  - Orange/brown
 CAN High - Orange/black

This example below is from a Scirocco connecting to the wires at the CAN gateway.
