NOTICE
Do not remove or install the master cylinder assembly without first positioning a 5/32-inch (4 mm) thick insert between the brake lever and lever bracket. Removing or installing the master cylinder assembly without the insert in place may result in damage to the rubber boot and plunger on the front stoplight switch. (00324a)
NOTE
A section of corrugated cardboard or the eyelet of an ordinary cable strap can be used for this purpose.

  1. See Figure 1. Place a 4 mm (5/32 in) thick insert between the brake lever and the lever bracket.
  2. Refer to the service manual and follow the instructions to remove the right-side hand control from the vehicle. For models with cruise control, see Figure 2. Use the switch knob removal tool (9) from the kit to remove the OE cruise control switch knob (7). Discard the knob.
  3. For 2007 and later models:Trace the right-side switch wiring harness to the black six-way pin housing [22A] (A) (and for 2008 and later models with cruise control, the brown or black three-way pin housing [159A]) (B), and unplug the connector halves. For 2006 and earlier models:Trace the right-side switch wiring harness to the black six-way socket housing [22B] (A), and unplug the connector halves.
    4. NOTE
    DO NOT remove the wires from the mating connector housing(s) inside the headlamp nacelle.
  4. Note the wire colors and positions in each cavity of the connector housing(s) (A and B) on the switch harness. Follow service manual instructions to remove the wires and terminals from the housing(s), and set the housings aside for later assembly. Mark the connector housings to identify them as coming from the right-side assembly.
  5. Follow service manual instructions to disassemble the right-side switch control housing. Retain the upper (C) and lower (D) housing halves, internal switch mounting brackets (F) and the housing attaching hardware (G).
    6. NOTE
    If a Chrome Handlebar Switch Cap Kit has been installed on the handlebar controls, remove the switch caps (E) per the instructions in that kit, and set them aside for later assembly.
  6. Discard the removed handlebar switch set with harness and the hardware that secured the internal switch mounting bracket (F).
    7. NOTE
    The switch sets are side-specific. The right-side switch set has upper switches labeled "START" and "OFF/RUN".
  7. Get the new right-side handlebar switch set and harness assembly (1).
    8. NOTE
    If new or previously fitted chrome handlebar switch caps (E) are being installed on the new switches, follow the instructions in that kit to replace the black caps.
  8. Follow service manual instructions to assemble the switch set and right-side switch housing, using new screws (5 and 6) from the kit, and screws (G) saved earlier. A new stoplamp switch V-clip (10) is also included in the kit for use if the OE clip was damaged during removal.
  9. For models with cruise control, install the new SET/RESUME switch knob (7).
The new right-side handlebar switch set and harness assembly has wires that are approximately 150 cm (60 in) in length, with Molex pin terminals at the ends.
The wires will be cut to a length determined by the handlebar, and new terminals (provided in the kit) will be installed. See Table 1.
NOTE
If an unlisted handlebar and/or riser are used, it will be necessary to fully route the harness to determine the new cut length.
In ALL cases, cut the harness wires to the appropriate length only after providing for slack throughout the full range of steering motion.
Make sure to cut the harness wires to a suitable length to easily reach the mating connector housings inside the headlamp nacelle.
For motorcycles with internally wired handlebars: Route the harness through the handlebar before cutting the wires.

Return to Service
WARNING
Be sure that steering is smooth and free without interference. Interference with steering could result in loss of vehicle control and death or serious injury. (00371a)
  • Be sure wires, clutch cables, throttle/ idle cables and brake lines do not pull tight when handlebars are turned fully to left or right fork stops.
1. Assemble the headlamp nacelle following service manual instructions..
NOTE
Verify that the ignition key switch is in the OFF position before installing the main fuse or attaching the negative battery cable.
2. Models with main fuse: Refer to the service manual and follow the instructions to install the main fuse. Models with main circuit breaker: Refer to the service manual and follow the instructions to attach the negative battery cable. Apply a light coat of Harley-Davidson electrical contact lubricant (H-D Part No. 99861-02), petroleum jelly or corrosion retardant material to the negative battery terminal.
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)
3. Refer to the service manual, and follow instructions to install the seat.
4. Turn the ignition key switch to IGNITION, but do not start the motorcycle. Test each handlebar switch for proper operation. Test for proper headlamp, turn signal, tail lamp and stop lamp operation. Turn the handlebar to the left and right steering stops, testing the handlebar control functions at each stop.
