You need to connect 4 wires to the bike’s wiring harness. Good quality quick connectors are supplied (4 pcs wire taps). No need to cut any wires and no need for soldering.
All connections can be done either under the fuel tank, at the ECU box or behind the instrument cluster.
To complete the install, it is recommended that you consult with your dealer and/or refer to the Service Manual available for your bike.
Due to the large number of bike models and vehicles compatible with this Kit, model specific wire colors and install instructions are not described in this document.
1. The ignition key should be in OFF position. Remove the seat, raise and support the fuel tank
2. Locate the Speed Sensor coupler.
A. Most motorcycles have the speed sensor mounted on the gearbox. Others have the sensor mounted either at the front or at the rear wheel.
B. Trace the cable until you find the speed sensor coupler. It is a 3-pole connector (except BMW, which use 2-pole).
C. If in doubt, check the bike’s Service Manual or ask your dealer for the location of the Speed Sensor coupler.
Separate the Speed Sensor coupler. Rotate the wheels while the ignition is on. The speedometer should indicate 0. If so, turn the ignition off, reconnect the coupler and proceed to the next step. Otherwise, if the speedometer registers a speed other than 0, you have not disconnected the correct coupler and need to look again.
Some bikes equipped with ABS do not have a speed sensor (e.g. Yamaha FJR1300 2006+, VMAX 2009+, Ducati ST4 2005+). The speed signal is generated by the ABS computer.
On these bikes, tap the speed signal wire between the ABS computer
and ECU box. Refer to the bike’s Service Manual for the wiring.
3. Connect the GFYSHIP Black wire to the Ground wire of the sensor, using the Red wire tap connector supplied.
Usage: Place the unstripped run wire (sensor ground) inside the run
channel. Close the side cover until latched. Cut off the excess length, then
insert the unstripped tap wire (Black) completely and check its position.
Insert the blade (u-contact) and press down by finger pressure. Then, fully
depress the u-contact with pliers. Close the hinged top cover until latched.
Alternatively, connect the GFYSHIP Black wire to chassis ground.
4. Connect the GFYSHIP Red wire to a switched +12V power lead, such as the hot wire of the rear brake light switch, or to a power lead at the fusebox. You can use the Power lead of the speed sensor if its voltage is higher than 9V.
Again, use the Red wire tap connector supplied.
5. Check whether the Power and Ground connections are correct:
Select Neutral and turn ignition On
The GFYSHIP display should count from 6 to 1, then “L” flashes slowly.
(If not, the display is not receiving power and/or ground.)
6. Connect the GFYSHIP White wire to the Signal wire of the speed sensor (or to the speed signal wire from the ABS computer). As before, use the Red wire tap connector supplied.
7. Connect the GFYSHIP Green wire to the Signal wire of the Crankshaft sensor (Pickup coil). The Crankshaft sensor is inside the crankcase, usually near the alternator. It has two wires. Alternatively, tap the tacho signal wire near the ECU box. Again, use the Red wire tap connector supplied.
