HEX ezCAN for BMW

Frequently Asked Questions

HEX ezCANs have been developed for a wide range of controller area network (CAN-bus)-equipped BMW motorcycles.

Click here to see the current list of BMW motorcycles for which HEX ezCANs have been developed.

With advancing technological developments, as well as ongoing demand for new features and more functionality, HEX ezCAN design has evolved. This page lists the differences in hardware and software between the different HEX ezCAN iterations.

IMPORTANT: Generation I HEX ezCANs are no longer in production. All HEX ezCANs currently in production are Generation II.

HEX ezCAN for BMW, Generation I (2-wire)

HEX ezCAN 2-pin connector and plugs

This iteration of HEX ezCAN used two-pin Superseal connectors (above), with the following components:

  • Male 2-pin Superseal connector:
    • Plug: TE 282104-1
    • Pin crimp: 282109-1

On all power circuit connectors:
The red, orange, yellow and white wires (wire number 1) are the positive wires for each power circuit.
Wire number 2 (the black wire) is the negative/ground wire.

HEX ezCAN for BMW, Generation I (3-wire)

HEX ezCAN 3-pin connectors and plugs

This iteration of HEX ezCAN used three-pin Superseal connectors (above), with the following components:

  • Male 3-pin Superseal connector:
    • Plug: TE 282105-1
    • Pin crimp: 282109-1
    • Wire seal: 281934-2
  • Female 3-pin Superseal connector:
    • Plug: TE 282087-1
    • Pin crimp: 282109-1
    • Wire seal: 281934-2


HEX ezCAN Generation II (3-wire)

This is the current iteration of HEX ezCAN. It uses three-pin Sumitomo MT connectors (above) with the following components:

  • Sumitomo MT male connector:
    • Plug: 6187-3232
    • Terminal: 1500-0105
    • Wire seal: 7160-8234
  • Sumitomo MT female connector:
    • Receptacle: 6180-3242
    • Terminal: 1500-0110
    • Wire seal: 7160-8234

Since the HEX ezCAN entered production, modifications have been made to the control wiring and power circuit wiring specifications. The specifications of all wiring are given below.

IMPORTANT: Generation I HEX ezCANs are no longer in production. All HEX ezCANs currently in production are Generation II.

HEX ezCAN Generation I

  • Two-wire versions:
    • All output wires are 17 AWG (1.0 mm²)
  • Three-wire versions:
    • High-power output wires (red & orange) are 16 AWG (1.5 mm²)
    • Low-power output wires (yellow & white) are 17 AWG (1.0 mm²)
    • Control wires for 3-wire lights (red with white tracer and white with black tracer) are 18 AWG (0.75 mm²)


HEX ezCAN Generation II

  • High-power output wires (red & orange) are 16 AWG (1.5 mm²)
  • Control wires for 3-wire lights (red with white tracer and white with black tracer) are 18 AWG (0.75 mm²)

Yes, you can.

For detailed model-specific instructions on how to operate front auxiliary lights on the move (including turning the lights on and off, adjusting light intensity levels, temporarily switching off all front and rear lights, and strobing front auxiliary lights when the bike’s ‘Flash-to-pass’ button is pressed), refer to the Operating auxiliary front lights section of the HEX ezCAN User Manual. Download the user manual from the Software page at this link.

The second-generation HEX ezCAN evolved from a growing demand for more features and adaptability, and also that HEX ezCANs be made available for more makes beside BMW.

This led to a number of radical design changes being made on Generation II HEX ezCANs. Some of these are as follows: 

  • The main difference between Generation I and Generation II HEX ezCANs is their power circuits.
    • Generation I HEX ezCANs have two high-power output circuits with maximum output of 10 Amps each, and two low-power output circuits with maximum output of 4 Amps each.
    • Generation II HEX ezCANs have four high-power output circuits with maximum output of 10 Amps each.
  • Generation II HEX zCANs also have a number of other features not present on Generation I:
    • Support for up to two individually operated sets of auxiliary front lights. This allows you to change the intensity of each set of lights individually, and turn one or both light pairs on and off while on the move.
    • Support for auxiliary turn signals.
    • Support for heated gear.
    • Support for run/brake/turn lights.
    • Support for other types of 3-wire accessories, such as the Innovv K2 Dashcam.
    • Support for auxiliary front fog lights (in conjuction with the HEX ezSWITCH).
    • Support for Scottoiler automatic chain lubrication systems.
    • Support for up to 16 individual smart accessories, through the ezBUS (white) power circuit.
    • Ability to disable unused power circuits.

If you have any questions regarding HEX ezCAN functionality, please feel free to contact us for more information.

Yes, you can. A number of other HEX ezCAN users have done this before.

To connect factory-fitted BMW auxiliary lights to the HEX ezCAN, do the steps that follow:

  1. Disconnect your factory-fitted BMW auxiliary lights from the BMW’s wiring harness.
  2. Cut the factory harness connectors (below) off the BMW auxiliary lights.

  3. Connect the spotlight’s red wire with blue tracer to the orange (power) wire of a HEX ezCAN male two-wire MT connector.
  4. Connect the spotlight’s brown wire to the black (Ground) wire of the male MT connector.
  5. Insulate the cut ends of the BMW auxiliary light’s violet and orange wires. These wires must not be connected to the HEX ezCAN.
  6. Switch OFF Three-Wire Dimming Mode in the correct Auxiliary Lights section of the HEX ezCAN configuration software.
