Installation tutorial for the Sharkset LED Deck


This installation guide will walk you through the necessary steps to install the Sharkset LED deck as well as the turn signals and horn. This is the English version. We have also written a German version: click here!

Here is our YouTube video that complements this installation tutorial nicely:

Additionally recommended materials for installation:

  • Work gloves
  • Workbench (or a table edge with a pad as an alternative)
  • Heat gun / Lighter
  • Cable ties
  • Tweezers
  • Pliers
  • Wrench (size 10)
  • Security Torx bit set, to more quickly remove the screws of the battery cover and the footrest (otherwise, appropriate tools are included)

Before the installation, you should:

  • Read through the instructions carefully and, if possible, watch our installation video
  • Check the contents of the package
  • Remove the scooter’s rubber mat
  • Remove the protective films from the polycarbonate plate
  • Unscrew the scooter’s bottom plate

Electronics overview

  • Y-cable: Connects the scooter’s battery to the controller and the wiring harness.
  • DC converter: Converts the battery voltage to the voltage required for the LEDs (12 V).
  • Wiring harness: Various cables for supplying power to the turn signals, horn, and LEDs.

Step-by-step installation

Step 1: Remove the bottom plate and prepare cables

Start by removing the bottom plate of the scooter, if not already done.

Then, ensure to disconnect the XT60 connector from the battery to cut off power to the rest of the scooter (this will void the warranty from Ninebot). Begin by connecting the supplied Y-cable with XT60 connectors to the controller, using the female XT60 connector on the Y-cable.

Step 2: Connect the DC converter

Connect the black plug on the Y-cable to the input of the DC converter. This converts the voltage from the battery to 12 volts, which is needed for the LEDs etc.

Step 3: Prepare connections

Connect one end of the wiring harness (with three connections, for the deck, horn, and turn signals) to the other end of the DC converter.

Then connect the cables for the LEDs, horn, and turn signals to their respective connections. The choice of connection here does not matter, as it only supplies power. You can also perform this step later to make the cable management a bit easier.

Ensure to always connect the plug with the red and black cables.

Disconnect the plugs to the LED strips to have more space to work. The LED strips will be needed later on.

Step 4: Prepare turn signals

Screw each turn signal onto the Sharkset rear suspension. Route the cables along with the motor cable bundle through the grommet into the scooter.

Later, you should use cable ties to secure the turn signal cables and prevent them from slipping.

Step 5: Connect the ground wires of the turn signals

Take the supplied heat-shrink tubing, thread the two ground wires (black) of the turn signals through it, and connect the ground wires to the black cable with two exposed sockets on the turn signal wiring harness.

Slide the heat-shrink tubing over the connection and heat it with a heat gun or lighter, so the tubing protects the connection.

Step 6: Connect the positive wires of the turn signals

Take the plug on the yellow cables of each turn signal and thread the two smaller supplied heat-shrink tubings through it.

Insert the two plugs into the two green sockets hanging on the yellow cables of the turn signal wiring harness. Do not heat the heat-shrink tubings just yet.

To know where to connect the left or right turn signal, you will need to test it later using the control switch.

Step 7: Connect everything else

Connect the plug with the two black cables on the horn (ground) to the socket with the red-blue cables on the turn signal wiring harness.

Connect the turn signal relay (with the large white socket) to the large white plug on the wiring harness. The clip secures the connection.

To determine where to connect the left or right turn signal, now connect the switch and plug the XT60 connector from the battery into the Y-cable. Activate the turn signal. If the turn signals respond backwards, swap the positive wires.

Once you are certain the wiring is correct, heat the heat-shrink tubing on the positive wires of the turn signals to secure the connection.

Care must be taken with fire and heat, especially near the battery.

Route the connections for the LED strips out of the scooter through the angled tube. For this, the rubber plug must be removed. To reinstall it later, it will need to be cut/enlarged.

Safely store the horn inside the scooter and arrange the cables so that the bottom cover can be installed without issues later.

The horn can, for example, point forward towards the angled connecting tube. If the horn is placed behind the plug, the volume will not be very high. In front of the plug in the angled tube, the volume is higher, but the water resistance is significantly worse. This is a decision you must make for yourself.

Step 8: Install the switch

Route the long cable with the green Julet connector from inside the scooter along with the dashboard’s data cable out of the scooter, back into the handlebar, and out again along with the brake cable.

Alternatively, you can route the cable through the handlebar stem into the handlebar, which is more complex as it requires removing the dashboard among other things.

Install the switch on the handlebar to control the horn and turn signals.

If you want to place the switch directly next to the grip, you just need to pull off the grip beforehand. For components with cables (e.g., the thumb throttle), you must first disconnect the respective connector from the dashboard before you can remove them.

Connect the green Julet connector of the switch assembly with the other end coming out of the scooter.

Secure the cables as needed, e.g., with cable ties.

Step 9: Testing

Connect the XT60 connector of the wiring harness to the battery, if not already done. Test all functions and ensure that the turn signals are being correctly controlled. If everything fits, you can disconnect the power supply again.

Remember to heat the heat-shrink tubing on the positive wires of both turn signals to secure the connection, if not already done.

Step 10: Prepare the board

Stand the scooter upright. Remove the scooter’s rubber mat if not already done, as the design is intended for the G30 without a foot mat.

Now, peel off the protective films on the Sharkset LED board, if not done previously.

Turn the Sharkset board so that the groove/notch faces upwards and forwards. Place the LED strips into the groove and route the cables out of the board.

You can choose in which direction to place the LED strips. The simpler method is to stick them into the groove, but this does not utilize the full potential of the LED brightness, and the board appears less bright.

If the LED strips “face into the board,” it will definitely be brighter in the end.

Once you’ve decided on a direction, take the large adhesive pad with the yellow side up and stick it onto the board to secure the LED strips. The white end points towards the cables coming out of the board.

Step 11: Mount the board

Place the board and the aluminum plate on the foot surface, making sure not to pinch any cables. The cables should face forward and be routed through the angled connecting tube between the handlebar and frame. For this, the existing rubber plug must be removed or later cut/enlarged.

Select the aluminum holders and the shorter of the supplied pan-head screws. The holders will be installed at the front and back on both the left and right sides. The middle holes in the Sharkset board will not be used.

Place the aluminum holders (with the bend facing inwards) against the scooter frame and align them with the corresponding holes of the Sharkset deck. Now, slightly screw in each holder with the screws and an Allen key, but not tightly yet.

On the front left, at the footrest, the holder also serves as a spacer for the rest, which extends the stand so the scooter is less likely to tip over. Here, you must loosen the two security Torx screws at the stand, place the aluminum holder underneath, and secure the footrest with the holder underneath using the two supplied countersunk screws with Allen heads.

For the other aluminum holders, we do not use the lateral through-holes. They are there to enable you to further secure the board by drilling holes into the frame of the scooter, however, the lateral mounting on the footrest is already sufficient.

It may happen that the holder on the back right blocks the charging port slightly. If this is problematic for you, you can instead place this one holder in the middle.

After securing the four holders, insert a pan-head screw with an Allen head through the board at the very front left and right. They are fixed below with the supplied nuts, which better prevents slipping between the metal plate and the polycarbonate board.

If you have a Sharkset rear suspension, you can additionally take the two remaining longer pan-head screws, pass them through the rear two through-holes, and secure them below with a nut each. However, this is not necessary.

Now that the board is correctly aligned, tighten all screws.

Step 12: Secure the turn signal cables

Secure the turn signal cables with cable ties to prevent slipping and contact with the motor.

Don’t forget to remount the bottom plate (ensuring not to pinch any cables) and reinstall the rubber plugs 😉

Finished! Enjoy your new board! 🎉🛴
