Find your bike's RDC connector and battery
Open the compartment under pillion seat
Look inside, towards the rear, of the area under the pillion seat
DO NOT confuse the RDC connector with the ABS tilt sensor!
RDC connector is located under the rear cowling.
Remove the seat to reach the RDC.
Look underneath the cowling.
Do not confuse the RDC and the ABS tilt-sensor.
The R1200RS RDC connector is underneath the pillion seat.
Look towards the front of the bike, on the left side, hidden under the cowling, you will find the RDC connector.
The RDC connector is hidden from plain sight.
Remove the pillion seat to reach the RDC.
After removing the pillion seat, look under the cowling towards the front of the bike.
This is what the RDC plug looks like.
Install and configure the software
Download and install the HEX ezCAN configuration software from the Software page.
Our Software page sets out the process of configuring the installation with the HEX ezCAN configuration software.
Connect your ezCAN to the computer and make sure your unit has the latest firmware.
Determine the channel configuration, see below.
Install the ezCAN under the seat
You can secure the ezCAN with the velcro strips provided after the accessories have been plugged in.
Route and connect the battery wires
Disconnect the battery wiring harness terminals from the battery and connect the ezCAN wires to the battery before re-connecting the factory wires.
HEX ezCAN Power supply cables
IMPORTANT NOTE: First, unplug the battery negative wire and only attach it at the end again. This is good practice whenever you work on your bike's electronics. For ease of installation, it is recommended that you connect the ezCAN's positive wire to the jumpstart terminal, but you can also connect it to the battery positive terminal.
Plug the ezCAN into CAN-Bus
Bike with RDC control unit
- Start by unplugging the CAN-Bus connector from the RDC control unit if it is not yet unplugged.
- Plug the HEX ezCAN into the CAN-Bus connector - inline.
- The HEX ezCAN has two CAN-Bus connectors, one male and one female. Plug the male connector into the CAN-Bus connector, with the female connector going into the RDC control unit.
Bike without RDC control unit
- Start by unplugging the cap from the RDC - CAN-Bus connector.
- Plug the Male HEX ezCAN into the CAN-Bus connector - inline.
- Replace the cap on the female HEX ezCAN terminal.
IMPORTANT NOTE: Both the male and female ezCAN CAN-Bus terminals must be connected correctly. Do not connect to any other component or to any other part of the motorcycle's wiring harness. If you do, the ezCAN will not function.
Connect accessories using colour-coding
The HEX ezCAN kit includes eight stub connectors with male connection terminals. Four of the stub connectors have three wires while the remaining four connectors have two wires.
Three Wire stub connector
Three wire stub connectors
If your auxiliary lights have three wires use the three wire stub connectors. If not the two-wire stub connectors must be used for accessories that have power and ground wires only.
If you are not going to use one or more of the power output channels, it is recommended that you install a blanking plug over the unused output. The HEX ezCAN product contains two blanking plugs.
The colour-coding on the output wires must match the colours in the output configuration you select from the HEX ezCAN channel mapping software. Red to red, orange to orange, etc. (Black wire is Battery Negative and the Red, Orange,Yellow and White are the Positive Supply.)
Connect the terminals of the high-power and low-power stub connectors to the correct female terminals on the ezCAN.
Connect the spotlight’s ground wire to the ground wire of the stub connector.
If you are installing spotlights equipped with a third wire for light-intensity control, connect the spotlight control wire to the control wire of the stub connector. If the spotlight only has two wires, use the two wire stub connectors.
Test the installation
Most newly installed accessories can be tested simply with the ignition "ON", but some brake functions will require the bike to be in motion and traveling above a certain speed. For example, emergency braking requires deceleration of more than 21km/h/s (kilometres per hour per second).
SAFETY NOTICE: Test and check your installations and accessories in a safe, controlled environment. Caution is advised at all times. Extra vigilance is required when testing new features or accessories. You do so at your own risk.
