On BMW R1200 LC and R1250 models (K5x), the HEX ezCAN is controlled through the bike’s RDC (tyre-pressure monitoring system) connector, whether or not the bike is equipped with the optional RDC system.
BMW R1200 LC and R1250 models have a number of important differences in terms of component placement and disassembly/re-assembly procedure.
Always follow the instructions in the drop-down for the correct model below.
Step 1: Locate the RDC connector
Remove the rider and pillion seats.
On earlier R1200GS LC and R1200GS Adventure LC models, the RDC connector is easily accessible under the pillion seat, in front of the tail light (lower portion, above).
Later R1200GS / GS Adventure LC models and all R1250GS / GS Adventure models are equipped with a lean-angle sensor. Connect the HEX ezCAN to the RDC connector only (✅, above). Do not connect the HEX ezCAN to the lean-angle sensor connector (X, right).
Step 2: Locate the vehicle battery
Remove the triangular black trim panel on the right side of the bike, below the fuel tank, to access the battery (below).
Step 1: Locate the RDC connector
If the top box is installed, remove the top box.
Remove the rider and pillion seats.
The RDC connector is located behind the pillion seat, under the topbox mounting rack (below).
Later-model R1200RT LCs and all R1250RTs are equipped with a lean-angle sensor. Connect the HEX ezCAN to the RDC connector only (✅, below). Do not connect the ezCAN to the lean-angle sensor connector (X, below).
A typical view of the RDC connector is shown below.
Step 2: locate the vehicle battery
Remove the triangular black trim panel on the right side of the bike, below the fuel tank, to access the battery (below).
Step 1: Locate the RDC connector
Remove the rider and pillion seats.
The RDC connector is located under the pillion seat latch, between the rider and pillion seats (below).
A typical view of the RDC connector is shown below.

IMPORTANT: Do not connect the HEX ezCAN’s CAN-bus connectors to any part of the motorcycle other than the RDC wiring harness connector and, if applicable, the RDC module. If you do, the HEX ezCAN will not function.
In the case of BMW R1200 LC and R1250 models, it is generally advisable to install the main body of the HEX ezCAN in close proximity to the location of the BMW RDC module or RDC resistor plug.
Ensure that all HEX ezCAN wiring is routed safely and securely, in a way that does not allow it to chafe or pinch. Where needed, secure all wiring to frame tubes or other components using the cable ties supplied with the HEX ezCAN installation kit.
Depending on whether your bike has the BMW RDC system fitted, the RDC connector will be seen in one of two configurations:
If your motorcycle does not have the BMW RDC system:
A resistor plug will be connected to the RDC connector.
If your motorcycle has the BMW RDC system:
The RDC connector will be plugged into the RDC module.
HEX ezCAN cable routing may depend on a number of factors, including your personal preference.
Ensure that the wiring is routed safely and securely, in a way that does not allow it to chafe or pinch. Where needed, secure all wiring to frame tubes or other components using the cable ties supplied with the HEX ezCAN installation kit.
WARNING: For safety reasons, always disconnect the negative battery terminal first, and re-connect it last.
1. Start the installation by locating the main body of the HEX ezCAN in a place that allows straightforward, logical wiring runs. We recommend installing the HEX ezCAN main body in close proximity to the BMW RDC module, as this allows easier access for firmware updates and diagnostics.
2. Disconnect the negative wiring harness terminal from the negative battery pole.
3. Remove the two Torx screws securing the rear of the fuel tank (red arrows, left image below).
4. Remove the two Torx screws securing the front seat support retaining bracket (green arrows, left image below).
5. Unclip the fuse holder (blue arrow, left image below) from its retaining mount.
6. Remove the Torx screw above the bike’s positive jumper terminal (red arrow, right image above).
7. Unclip the ezCAN fuse holder lid from the fuse holder, and temporarily remove the fuse.
8. Gently lift the front seat support retaining bracket and the rear of the fuel tank by about 10 millimetres (0.4 inch). This creates enough space to slide the ezCAN power cables underneath these components.
9. Route the ezCAN fuse holder and power cables along the right rear upper main frame tube (right image above), then downwards behind the tube. Gently pressing the cable routing tray inward behind the upper frame tube creates enough space to slide the fuse holder between the tray and the tube.
10. Remove the black plastic battery retaining bracket, and unhook the rubber battery retaining strap.
11. Pull the battery free of the frame. The battery’s positive terminal will be exposed.
12. Disconnect the positive wiring harness terminal from the positive battery pole.
13. Connect the terminal on the orange ezCAN power cable, and the bike’s positive wiring harness terminal, to the positive battery pole.
14. Connect the terminal on the brown ezCAN power cable, and the bike’s negative wiring harness terminal, to the negative battery pole.
15. Tidy the CAN-bus and battery cable routing. Secure all loose cables using the cable ties included in the HEX ezCAN installation kit, making sure you have easy access to the four power circuit plugs.
Note: The HEX ezCAN’s status LED should be solid green for approximately a minute after connection to the battery. After this time, the HEX ezCAN enters Sleep Mode, and there will be no LED activity until the bike’s ignition is switched ON.
The HEX ezCAN installation kit includes four two-wire stub connectors with male connection terminals, orange power wires and black ground wires.
The following parts are also included:
If the accessory to be connected to a power circuit has three wires, convert a two-wire stub connector to a three-wire connector as shown in the Connecting 3-wire LED lights section of the HEX ezCAN User Manual (downloadable from here).
If the accessory to be connected to a power circuit has two wires, seal the stub connector’s empty terminal cavity as shown in the Connecting 2-wire accessories section of the HEX ezCAN User Manual.
If any of the HEX ezCAN’s power circuits will not be used, we recommend that you connect a blanking plug to the output plug of each unused circuit.
Connect the male terminal of each stub connector to the relevant female HEX ezCAN power circuit connector (below).

Read the HEX ezBUS and Configuring HEX ezBUS functionality sections of the HEX ezCAN user manual (downloadable from here) for detailed information on how to use ezBUS functionality.
If you are installing ‘smart’ accessories (that is, low-power accessories capable of intelligent input and control through the HEX ezCAN’s LIN bus), note the following:
Read the HEX ezBUS and Configuring HEX ezBUS functionality sections of the HEX ezCAN user manual (downloadable from here) for detailed information on how to use ezBUS functionality.
Note that if the white circuit is set to ezBUS mode, its fuse trip limit is set to 15 Amps by default. If needed, ezBUS PWR functionality can be used to increase the white circuit’s current capacity to a maximum of 30 Amps in ezBUS mode. See the relevant section of the HEX ezCAN User Manual for details.
IMPORTANT: If the stub connectors included in your HEX ezCAN installation kit do not have orange power wires, but instead have colours that match the colouring of the HEX ezCAN power circuits (as seen below), always connect like-to-like (red stub connector to red power circuit, blue stub connector to blue power circuit, and so on.)
The HEX ezCAN Extension Kit contains everything you need to connect front auxiliary lights, rear accessory lights and a horn to the HEX ezCAN. It also includes additional connectors that allow you to connect other accessories.
