STEP 1:

DOWNLOAD, INSTALL & CONFIGURE THE SOFTWARE

This is a good time to:

  • Unbox the ezCAN.
  • Decide what and how many accessories you will be installing, and their requirements. Must some accessories be connected in a specific manner and/or to specific power circuits? As an example, low-powered ‘smart’ accessories must typically be installed on the ezBUS (White) power circuit.
  • Read the Installing for Life section of the ezCAN User Manual (downloadable from here), and evaluate your planned installation according to the guidelines in that section.
  • Register your ezCAN (All you need to do to register the ezCAN is connect it to your computer using the supplied USB cable, meaning you can do it at the comfort of your desk.)

STEP 2:

LOCATE THE DIAGNOSTIC CONNECTOR AND BATTERY

Needed tools:

  • T30 Torx driver
  • T40 Torx driver
  • 10mm wrench or socket

Step 1: Locate the diagnostic connector

To access the diagnostic connector:

1. Remove the front and rear seats.
2. The diagnostic connector is located on the left side of the bike, approximately between the front and rear seat (red arrow, below).

For easier battery and accessory wiring placement (broken green line, above), we recommend temporarily removing the left-side plastic panel between the seat and fuel tank (yellow arrow, below). This panel is secured by two T30 Torx screws.

Step 2: Locate the battery

Locate the vehicle battery as follows:

  1. Use the T40 Torx driver to remove the four screws securing the motorcycle’s skid plate (yellow arrow, below).

3. Remove the skid plate.
4. The battery is located in front of the engine, below the radiator (below).

STEP 3:

PLUG THE ezCAN INTO THE CAN-BUS

IMPORTANT: Do not connect the ezCAN’s CAN-bus connector to any part of the motorcycle other than the diagnostic connector. If you do, the ezCAN will not function.

  1. Install the main body of the ezCAN in the vicinity of the bike’s diagnostic connector.
  2. Remove the protective cap from the bike’s diagnostic connector.
  3. Connect the white JWPF plug on the Harley-Davidson Euro 5 adaptor included in the ezCAN installation kit to the JWPF plug on the ezCAN’s CAN-bus connector.
  4. Connect the ezCAN’s male Euro 5 plug to the motorcycle’s diagnostic connector.

STEP 4:

CONNECT THE ezCAN TO THE BIKE'S BATTERY

Ensure that all 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 ezCAN installation kit.

WARNING: For safety reasons, always disconnect the negative battery terminal first, and re-connect it last. 

  1. Disconnect the negative wiring harness terminal from the negative battery pole.
  2. Disconnect the positive wiring harness terminal from the positive battery pole.
  3. Open the rubber lid of the ezCAN main fuse housing and temporarily remove the fuse. This will make it easier to route the ezCAN power cables and fuse housing through tight spaces.
  4. Route both ezCAN power supply cables forward from the ezCAN main body, along the left side of the bike, over the ABS unit and under the fuel tank mounting bracket (green arrow, below).

5. Route the power supply cables along the upper left side of the engine, then down toward the battery compartment (broken green line, below).

6. Route the power supply cables along the bottom front end of the engine, then toward the battery (broken green line, below).

7. Connect the terminal on the orange ezCAN power cable, and the bike’s positive wiring harness terminal, to the positive battery pole. Do not fasten the terminal at this time.

8. Connect the terminal on the brown ezCAN power cable, and the bike’s negative wiring harness terminal, to the negative battery pole. Do not fasten the terminal at this time.

9. Reinstall the ezCAN main fuse into the fuse holder (green arrow, image above), and close the rubber lid of the fuse housing.

10. Keeping skid plate fitment in mind, make sure the ezCAN battery cables are optimally positioned for final fitment.

11. Tighten the negative and positive battery terminals.

12. Starting at the location of the battery, secure the ezCAN battery cables using cable ties.

13. Secure the remaining length of the ezCAN battery cables using cable ties, following the battery cables from the battery, back toward the main body of the ezCAN.

14. Tidy the CAN-bus and battery cable routing, making sure you have easy access to the four power circuit plugs.

14. Secure all loose cables using the cable ties included in the ezCAN installation kit.

Note: The HEX ezCAN’s status LED should be solid green for approximately a minute after connection to the battery. After this time, the ezCAN enters Sleep Mode, and there will be no LED activity until the bike’s ignition is switched ON.

Tip: If you will be installing an auxiliary rear brake light, rear-mounted turn signal lights, or run/brake/turn lights, the bike’s rear mudguard has a rubber grommet that can be used to route accessory wiring from the ezCAN into the rear wheel well, following the bike’s factory wiring runs (broken green line, below).

STEP 5:

CONNECT THE ACCESSORIES, USING COLOUR CODING

The 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:

  • 4x pulse-width modulation (PWM) terminal wires (orange with white tracer)
  • 4x rubber blanking seals

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 ezCAN’s power circuits will not be used, we recommend that you connect a blanking plug to the output plug of each unused circuit.


2-wire applications: insert a blanking seal.
3-wire applications: insert a PWM terminal wire.

4x terminal wires and blanking seals
4x 2-wire stub connectors

Connect the male terminal of each stub connector to the relevant female ezCAN power circuit connector (below).

Connecting a 2-wire accessory to an ezCAN stub connector:

  1. Connect the accessory’s ground/Earth wire (this is usually, but not always black or brown) to the ground wire of an ezCAN stub connector.
  2. Connect the accessory’s power wire (this is usually, but not always red) to the 12V power wire of an ezCAN stub connector.


Connecting a 3-wire accessory to an ezCAN stub connector:

  1. Connect the accessory’s ground/Earth wire and power wire as described above.
  2. Connect the accessory’s PWM control wire to the dual-colour (solid colour+tracer) wire of an ezCAN stub connector.

Connecting low-power smart accessories to a power circuit:

If you are installing ‘smart’ accessories (that is, low-power accessories capable of intelligent input and control through the ezCAN’s LIN bus), note the following:

  1. Smart accessories (including the HEX ezSWITCH) must only be connected to the ezCAN’s ezBUS (white) power circuit. Smart accessories will not work if connected to the red, yellow or blue circuits.
  2. The ezBUS (white) power circuit can accommodate any odd or even number of individual accessories, to a maximum of fifteen.
  3. A selection of HEX ezBUS adaptors and connectors is available, allowing you to connect smart accessories quickly and easily. See the ezBUS Accessories section of the Hex Innovate online store for details.


Read the Hex ezBUS and Configuring Hex ezBUS functionality sections of the 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 ezCAN User Manual for details.

IMPORTANT: If the accessory stub connectors included in your ezCAN installation kit do not have orange power wires, but instead have colours that match the colouring of the 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.)

STEP 6:

TEST THE INSTALLATION

WARNING: Test and check your installations and accessories in a safe, controlled environment before first use. Caution is advised at all times. Extra vigilance is needed when testing new features or accessories. You do so at your own risk.

DISCLAIMER: Hex Innovate is not liable for any injury or damage, howsoever caused, and all products and services are used at your own risk.

Before finalizing the ezCAN installation or re-installing any components you may have removed, it is important that you test all newly installed accessories for satisfactory fitment and correct operation.

Many ezCAN-powered accessories can be tested by switching the ignition ON and operating the relevant controls. Exceptions include:

  • Accessories for which you have enabled the Only on when engine running feature (examples may include Aux 1 lights, Aux 2 lights, MotoLights, and heated clothing). To test these functions, the bike’s engine must be running.
  • Some brake light functions require that the bike be moving at or above a certain speed. As examples, Flash on Emergency Stop and Flash on Rapid Engine Braking functions require deceleration of more than 21 Kilometres per hour per second.

STEP 7:

COMPLETE THE INSTALLATION

Complete the ezCAN installation as follows:

  1. Make sure the main body of the ezCAN is well-secured in a place where it is protected from pressure, heat and impact.
  2. Make sure all factory, ezCAN and accessory cables and wiring harnesses are well clear of all moving parts, and securely fastened. Where needed, use the cable ties included in the ezCAN installation kit.
  3. Replace all motorcycle components and fasteners that may have been removed to facilitate the ezCAN installation.
  4. Inspect the complete installation for mistakes or problems, and fix all problems that you have noted.
  5. Test all new accessories for correct operation a second time.
  6. If you have not already done so, download the ezCAN user manual from this page.
