This is a good time to plan your installation by:
Now that you have taken some time to think and plan your installation, you are ready to get your hands dirty (figuratively of course)!
The R 1200 GS’ DWA is located under the rear seat, under the cowling.
Remove both seats to expose the cowling underneath them.
You’ll need a T25 torx driver and a 10mm wrench to remove the cowling and the luggage plate.
The DWA connector is close to the brake light in the tail of the bike.
Your battery is easily accessed when you remove the seat.
Find your battery here. Remember to undo the negative terminal first and connect it last to avoid any risk to your bike’s electronics.
The horn is located on the right side of the bike, next to the front suspension coils.
This is the horn before it is connected to the HEX ezCAN.
Here the horn is connected to the HEX ezCAN.
Finally, we connect the horn extension wire to the matching wire on the ezCAN.
Open the compartment under pillion seat
Look inside, towards the rear, of the area under the pillion seat
RDC connector plugged in
DO NOT confuse the RDC connector with the ABS tilt sensor!
Battery location.
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!
The battery is located under the rider’s seat, just behind the fuel tank. Route both the ezCAN power supply cables 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.
Note: DWA is the German abbreviation for ‘Diebstahl Warnanlage’ (anti-theft alarm system)
On R 1200 R, R 1200 S, R 1200 ST and R 1200 RT models, you will see the DWA or anti-theft alarm system connections, in the small compartment under the rear half of the seat, in front of the taillight. Note the wiring harness plug connected to the DWA module. On R 1200 GS and R 1200 GS Adventure models, you must remove the plastic luggage rack located under the rear seat to access the DWA connections.
If your R1200 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.
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.
The HEX ezCAN kit contains a green wiring harness with one terminal pin, branching out to two sets of two terminal pins.
Find the standard BMW horn on your R-series motorcycle. On most models, the horn is located underneath the headlight or front fairing, near the Telelever suspension strut or fork. 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.
If you want to install an accessory horn, connect the accessory horn to the chosen high-power output stub connector on the ezCAN.
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
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.
The HEX ezCAN Extension Kit provides you with everything that you need to connect your front auxiliary lights, brake lights and horn to the ezCAN, with additional connectors to facilitate other accessories.
The kit contains:
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.
DISCLAIMER: HEX ezCAN is not liable for any injury or damage howsoever caused and all products and services are used at your own risk.
