Removing the Old Speedometer
- Apply power to the motorcycle and record the odometer reading.
WARNINGTo prevent accidental vehicle start-up, which could cause death or serious injury, disconnect battery cables (negative (-) cable first) before proceeding. (00307a)
WARNINGDisconnect negative (-) battery cable first. If positive (+) cable should contact ground with negative (-) cable connected, the resulting sparks can cause a battery explosion, which could result in death or serious injury. (00049a)
- Refer to the service manual and follow the instructions given to remove the seat and disconnect the battery cables, negative (-) cable first. Retain all seat mounting hardware.
- Remove the instrument console acorn nut (and mounting screw with a flat washer on some models). Place an H-D Service Cover or clean shop towels on the fuel tank. Lift the console from the fuel tank, turn it upside down and lay it on the covering.
- Unplug the 12-terminal connector [39B] from the back of the speedometer. Depress the external latches, and use a rocking motion to separate the pin and socket halves.
- Remove the back clamp. Gently pry the three latches upward to release the back clamp from the back of the speedometer.
- Unscrew the trip-meter reset button, and pull the harness from the clamp (remove the screw if necessary).
- Lift the console and remove the old speedometer from the console. Discard the old speedometer, but retain the rubber gasket and back clamp for use with the new gauge.
- Set the console securely on top of the fuel tank.
NOTE
Cover the fuel tank with an H-D Service Cover or clean shop towel to prevent scratching the finish.
NOTE
If necessary, bend back the flexible metal clip to free the harness conduit from the underside of the console.
NOTE
Set the console securely on the protected top of the fuel tank, and take care that it does not fall off during the following operations.
Installation and Final Check
NOTE
Apply window cleaning fluid or mild soapy water to the speedometer gasket as needed to aid installation.
| 1. | Turn the console over, facing upward. | |||||
| 2. | Place the speedometer gasket into position around the console speedometer bore. | |||||
| 3. | Fix the new gauge into the bore so that it fits snugly against the rubber gasket. Rotate the gauge into approximate visual alignment. The back clamp will complete the alignment. | |||||
| 4. | Turn the console over, face down. | |||||
| 5. | Install the back clamp. Place the back clamp over the back of the gauge, aligning the two slots with the console bosses. Press the latches down until they lock into position. | |||||
| 6. | Insert the trip-meter reset switch through the hole in the left side of the console. Retain the harness in the clamp, if used, and screw on the rubber button. | |||||
| 7. | See Figure 2. Route the harness from the gauge, and position the 12-terminal connector [39B] as shown. Carefully insert the connector into the back of the speedometer. Secure the harness with cable straps from the kit. |

If positive (+) cable should contact ground with negative (-) cable connected, the resulting sparks can cause a battery explosion, which could result in death or serious injury. (00068a) WARNINGAfter installing seat, pull upward on seat to be sure it is locked in position. While riding, a loose seat can shift causing loss of control, which could result in death or serious injury. (00070b) | ||||||

| 11. | Turn the ignition/key switch to IGN, but do not start the motorcycle. Test for proper turn signal, brake light and tail light operation. | |||||
| 12. | Check the speedometer and tachometer for proper operation. |
NOTE
The odometer on some kits will remain displayed when the ignition is in the OFF position.
Initialization
After installing the new gauge, the vehicle should receive a full tank of fuel in order to properly initialize the fuel range (miles to empty) functionality.
During consumption of the first full tank of fuel, the gauge software will begin the process of learning your riding patterns, eventually tailoring the fuel range calculations to your unique riding characteristics.
NOTE
After filling the fuel tank, the range function will not update until the vehicle resumes normal speeds.
Press and hold the "Trip" reset switch to toggle between the "mile" and "kilo" displays.
