STEP 1:

DOWNLOAD, INSTALL & CONFIGURE THE SOFTWARE

Watch a complete installation video here, or follow the step-by-step guide below.

STEP 2:

LOCATE YOUR BIKE'S BATTERY, DWA AND HORN CONNECTOR

Find DWA under the seat, towards the rear of the bike. Look in the rear compartment, under the seat, towards the tail of the bike. Close-up of the DWA connector. Battery is located under the top cover. Look for the horn connector on the left side of the bike, behind the radiator. Here we see the HEX ezCAN horn extention wire installed. Finally, we connect the horn extension wire to the matching wire on the ezCAN.


The F800S DWA connector is easy to find under the seat.


The horn is accessible if you reach down the left side of the fork.


Access the battery by removing the top body panel.


The DWA is located on the side of the fuel cap.

Remove this plug to install the ezCAN horn extension wire.


Here we see the ezCAN configured with the horn.


Finally, connect the horn extension wire to the matching wire on the ezCAN.

STEP 3:

INSTALL THE ezCAN UNDER THE SEAT

You can secure the ezCAN with the velcro strips provided after the accessories have been plugged in.

Important notice: If you can’t find the seat- you’re in trouble!

STEP 4:

ROUTE AND CONNECT THE BATTERY WIRES

The battery is located under the centre trim panel. Remove the seat and the centre trim panel by removing the six or eight screws. Route both the ezCAN power supply and ground cables along the motorcycle’s rear sub-frame and over the rear side of the engine airbox, to the battery. Disconnect the battery wiring harness terminals from the battery and connect the ezCAN wires to the battery before re-connecting the factory wires.

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.

STEP 5:

PLUG THE ezCAN
INTO THE CAN-BUS

  1. If your bike has a DWA, that is, ‘anti-theft alarm system’, you will see the DWA module in the small compartment under the rear half of the seat, in front of the taillight. Note the wiring harness plug connected to the module.
  2. Start by unplugging the CAN-Bus connector from the DWA control unit.
  3. The HEX ezCAN has two CAN-Bus connectors. Plug the male HEX ezCAN terminal into the CAN-Bus wiring harness and plug the female HEX ezCAN terminal into the DWA Control unit.

If your F800 does not have a DWA system, the end of the wiring harness plug will be covered by a plastic blanking plug containing an alarm-terminating resistor.

  1. Start by unplugging the cap from the DWA connector plug.
  2. Plug the male HEX ezCAN terminal into the CAN-Bus connector.
  3. Replace the cap on the female HEX ezCAN terminal.

That’s how easy it is!

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.

STEP 6: CONNECT THE GREEN HORN INPUT CONNECTOR (HORN TRIGGER WIRE)

Note: If you do not install the green horn input wire your high power accessory horn and Front auxiliary lights – strobe when horn active function will not work.

If you are going to install an accessory horn, connect the accessory horn to the chosen high-power output stub connector on the ezCAN. In order for the horn to work also connect the green horn trigger wire. The HEX ezCAN kit contains a green wiring harness with one terminal pin, branching out to two sets of two terminal pins.

(1) One terminal pin (2) Male two-pin plug (3) Female two-pin plug
Connect the end of the green wire with one terminal pin to the one-pin terminal on the ezCAN.

Find the standard BMW horn on your F-series motorcycle. Disconnect the motorcycle’s horn connection from the standard horn. Connect the male two-pin plug of the green wire to the horn connection on the BMW wiring harness.

Connect the female two-pin plug of the green wire to the standard BMW horn.

STEP 7:

CONNECT THE ACCESSORIES
USING COLOUR-CODING

The HEX ezCAN kit includes four two stub connectors (Orange) with male connection terminals. The stub connectors are made up of the following types:
– 4 x Two wire stub connectors (Orange)
– 4 x Terminal Wires 
(Orange)
– 4 x Blanking seals

If your auxiliary lights have three wires change the two-wire stub connector into a three-wire see the image below. If your auxiliary lights have two wires use the two-wire stub connectors for accessories that have power and ground wires only.

If you are not going to use one or more of the circuit functions it is recommended that you install a blanking plug over the unused output. The HEX ezCAN product contains two blanking plugs.

Insert blanking seal to use as a two-wire stub connector 
Insert terminal wire to use as a three-wire stub connector

4 x Terminal wires and Blanking seals
4 x Two Wire Stub Connectors

Connect the terminals of the high-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.

If you received four different coloured wires, please note the colour-coding on the output wires must match the colours in the output configuration you select from the HEX ezCAN circuit function software. Red to red, yellow to yellow, etc. Black wire is Battery Negative and the Red, Blue,Yellow and White are the Positive Supply.

  • 1 x 1.5m 2-core extension cable with spade connectors on one end (typically used to connect air horns or other 2-wire accessories)
  • 3 x female MT-3 connector kit including pins and wire seals
  • 5 x male MT-3 connector kit including pins and wire seals
  • 5 x blanking seals (where only 2 terminals are used in a 3-wire connector)

STEP 8: 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.
