Fitment: For Yamaha YZF-R6 1998-2016 For Yamaha YS250 Fazer ALL YEARS For Yamaha YZF-R6S 2006-2009 For Yamaha YFZ450 ALL YEARS For Yamaha YFM550 ALL YEARS Instructions : 1. Remove the seat and locate the Speed Sensor coupler. a. The Speed Sensor is usually located on the top of the gearbox and reads the revolution of the countershaft. b. The 3-pole speed sensor coupler is situated 20-40 cm (8”-16”) away from sensor. The connector is usually accessible under the fuel tank or removing a side fairing. If the speedometer is driven off the front wheel, the sensor coupler is usually in the headlight bucket. c. If in doubt, check the bike’s Service Manual or ask your dealer for the location of the Speed Sensor coupler. Confirmation: Separate the Speed Sensor coupler (you might need to use a small flathead screwdriver to get the coupler apart). Rotate the wheels 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 coupler, plug in both the male and female 3-pole GFY harness connectors. Make sure the connectors are fully seated. 3. Find the 2-pole natural (or black) color plug of the Crankshaft position sensor (Pickup coil). It has two wires coming from the crankcase: one is Gray, the other is usually Black/Blue - check the colors at both sides of the plug (if in doubt, do a temporary connection e.g. by using a thin needle to backprobe the connector pin). The 2-pole connector is usually under the fuel tank. for XVS1100 models only: find and use the Orange (ignition coil wire). Some Model Need To Find the 2-pole plug of the AC magneto (Crankshaft position sensor/Pickup coil). It has two wires coming from the crankcase: one is Red, the other is usually White 4. On the wire identified in the previous step, peel off the black sleeve (tape) near the 2-pole plug, leaving about 3 cm (1.2”) of the wire exposed. 5. Connect the GFY Black/Green wire to this bike wire, using the Red wire tap connector supplied. Usage: Place the unstripped bike wire 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. 6. Connect the GFY Red wire to a switched +12V wire, e.g. to the rear brake light switch, located under the fuel tank (2-pole brown or black connector, Brown wire at the main wiring harness side). Use the other Red wire tap connector supplied. You may also use e.g. the hot wire of the front parking light. Package Include: 1 x Gear Indicator ( Contains installation instructions )
