Locate the Speed Sensor connector.
Ducati: The Speed Sensor is mounted at the rear wheel. Trace the cable from the sensor until you find the 3-pole black speed sensor connector. The connector is usually accessible by removing the right side fairing and on most models it is in close proximity of the right side engine cover.
1. Separate the Speed Sensor connector (you might need to use a small flathead screwdriver to get the connector apart). Rotate the rear wheel while ignition is on. The speedometer should indicate 0. If so, turn the ignition off 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.
2. After separating the Speed Sensor connector, plug in both the male and female 3-pole GFYSHIP harness connectors. Make sure the connectors are fully seated.
3. Find RPM/Timing Sensor (Pickup) connector. The sensor is mounted either on top, or the side of the crankcase. Trace the cable from the sensor until you find the 3-pole connector.
Here is the connector location on some popular models:
Monster S2R, Multistrada: At the left side, above horizontal cylinder, ziptied to frame.
Monster S4RS: Behind left side cover under seat.
ST3: At the right side of engine, zip-tied to frame.
If in doubt, check the bike’s Service Manual or ask your dealer for the location of the RPM/Timing Sensor connector.
4. Disconnect the connector, and pull back the LARGER rubber boot from the plug, to leave the three wires exposed.
5. Route the GFYSHIP Black/Green wire through the rubber boot from the back. Make sure the wire will NOT touch the exhaust pipe or cylinder block.
6. Connect the GFYSHIP Black/Green wire to the wire in connector slot position 1, using the Red wire tap connector supplied.
Usage: Place the unstripped run wire (slot position 1) inside the run channel. Close the side cover until latched. Cut off the excess length, then insert the unstripped tap wire (Black/Green) 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.
