The Racing Dash2 digital dashboard display connects to a Link G4 ECU through CAN bus.
You need to locate the two CAN bus wires: CANH and CANL:
CAN High and CAN Low wires must be connected to the corresponding CANH and CANL wires on the Racing DASH2 preferably using a twisted pair cable.
Software configuration for CAN bus in PClink Software

Old CAN bus settings for Dash2 before 2022:
Software configuration on Racing DASH2
Connect the Racing Dash2 to a windows laptop using a USB to Serial adapter cable (not supplied)
Run the Configuration Software available from here.
Drag and drop parameters from the right “Data from ECU” to any position on the dash.
Press Save to keep settings.
If there is no CAN bus termination resistor inside the ECU it has to be added externally. Just connect a 120 ohm resistor between CANH and CANL wires somewhere close to the ECU.
