Service Manual Required
WARNING
Rider and passenger safety depend upon the correct installation of this kit. Use the appropriate service manual procedures. If the procedure is not within your capabilities or you do not have the correct tools, have a Harley-Davidson dealer perform the installation. Improper installation of this kit could result in death or serious injury. (00333b)
NOTE
This instruction sheet refers to service manual information. A service manual for this year/model motorcycle is required for this installation. One is available from a Harley-Davidson dealer.
Removing the Old Speedometer
  1. Apply power to the motorcycle and record the odometer reading.
WARNING
To prevent accidental vehicle start-up, which could cause death or serious injury, disconnect battery cables (negative (-) cable first) before proceeding. (00307a)
WARNING
Disconnect 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)
  1. See the service manual. Disconnect negative battery cable. Retain all seat mounting hardware.
  2. NOTE
    Cover painted parts to protect finish.
  3. Remove the instrument console acorn nut. 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.
  4. Unplug the 12-terminal connector [39B] from the back of the speedometer. Press the external latches, and use a rocking motion to separate the pin and socket halves.
  5. Remove the back clamp. Gently pry the three latches upward to release the back clamp from the back of the speedometer.
  6. Lift the console. 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.
  7. 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.
  8. Set the console securely on top of the fuel tank.
Installation and Final Check
NOTE
Apply window cleaning fluid or mild soapy water to the speedometer gasket 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 it fits snugly against the rubber gasket. Rotate the gauge into approximate visual alignment. The back clamp completes 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.
Carefully insert the connector into the back of the speedometer.

7.
Turn the console over, and center it on the fuel tank. Install the acorn nut. Tighten to 9–11.3 N·m (80–100 in-lbs).
8.
Apply a light coat of petroleum jelly or corrosion retardant material to battery terminals. Refer to the service manual and follow the instructions given to reattach the battery cables (positive cable first).
WARNING
Connect positive (+) 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. (00068a)
WARNING
After 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)
9.
Refer to the service manual, and follow instructions to install the seat.
WARNING
Be sure headlamp, tail and stop lamp and turn signals are operating properly before riding. Poor visibility of rider to other motorists can result in death or serious injury. (00478b)
10.
Turn the ignition switch to IGN, but do not start the motorcycle. Check operation of all lamps.
11.
Check the speedometer and tachometer for proper operation.
NOTE
  • Both the ECM and speedometer retain the odometer value. If the speedometer is replaced, it displays the odometer value stored in the ECM. The replacement speedometer will become locked to the ECM after 31.1 miles (50 km) have been accumulated. The trip B odometer displays the countdown mileage. Once the countdown reaches zero, the speedometer is locked to the ECM. If installed on another vehicle the odometer displays "VIN ERR". If the speedometer is removed from the vehicle before the countdown reaches zero, it has not been locked to the ECM. This mileage countdown allows for a road test to verify that speedometer replacement was the proper repair.
  • During the 50 km (31.1 mi) countdown period (before the speedometer is locked to the ECM), the security light flashes for up to 15 seconds when battery power is restored to the electrical system, while the new gauge synchronizes to the ECM.
  • Gear Indication display is a calculated gear position based on wheel and engine speed. The gear position displayed may be momentarily inaccurate depending on rider clutch use characteristics and clutch wear. This momentary false reading, although unlikely, can occur if the clutch is allowed to slip either due to excessive wear, poorly adjusted clutch or if the operator rides the clutch.
  • If gauge is installed on a motorcycle with ABS, verify that the ABS warning lamp is working properly. See the owner's manual for ABS warning lamp operation.
Backlight Color Modification
The backlight color can be modified for the entire gauge or the dial, speedometer pointer, tachometer pointer, and display separately (see Table 2 ). The gear indication and fuel level display can also be disabled.
1.
Turn ignition switch to ACC.
Figure 3. Fuel Level Display Setup
2.
See Figure 3. Press and hold both turn signals until fuel level bars are displayed with "ON/OFF" flashing. "SETUP" also appears. If "ON" is flashing, the fuel level display is enabled.
3.
To disable fuel level press and hold both turn signals until "OFF" is flashing.
4.

  5. The AM or PM then flashes. Choose correct one, then press and hold.
Battery Reconnection and Initialization
After the battery is reconnected or a new gauge is installed, the gauge requires about a half tank of fuel to properly initialize fuel range (miles to empty) functionality.
During consumption of the first full tank of fuel, the gauge software begins the process of learning your riding patterns, eventually tailoring the fuel range calculations to your unique riding characteristics.
The fuel level display and tank-mounted fuel gauge may not always match when starting with a full tank of fuel. The tank fuel gauge utilizes a continuous sweep needle to indicate fuel level, while the speedo/tach fuel level utilizes a segmented display. Each segment represents 1/8 of a tank. For example; if a given segment just came on or is about to go off, it would show no change, while the needle on the tank-mounted gauge would likely show a change in position.
Fuel Fill-up and Top-off
When adding fuel to the vehicle, it is recommended you add at least 7.6 L (2 USgal) of fuel to update the fuel and range displays. If the fuel display does not update immediately after the vehicle is put in motion the fuel and range displays slowly updates over the next 48.3 km (30 mi).
Press and hold the "Trip" reset switch to toggle between the "mile" and "kilo" displays.
