Turn signal sub-harness

Applicable to these part numbers:

Routing

  1. Route the turn signal harness such that it follows the main harness; continuing under the rear fender to the tail light.
  2. The 3 connection female spade connectors should be located under the fuel tank in the space provided by the frame.
  3. Route the gray/black wire up into the headlight bucket.

Inside the headlight bucket

  1. The gray/black wire with the 4 mm male bullet terminal is plugged into the bottom of the fuse block: into receptacle three (count from the left, as when facing the headlight bucket).

Under the fuel tank

  1. The white/black wire with the 6.3 mm female spade terminal is connected to the 3 connection female spade connector distributing current to the right turn signal circuit.
  2. The yellow/black wire with the 6.3 mm female spade terminal is connected to the 3 connection female spade connector distributing current to the left turn signal circuit.
  3. The purple wire with the 4 mm female bullet terminal is connected to the purple wire with the 4 mm male bullet terminal from the right handlebar switch.

At the battery tray

  1. The gray/black wire with the 6.3 mm female spade terminal is connected to the positive terminal (X or +) on the flasher.
  2. The purple wire with the 6.3 mm female spade terminal is connected to the load terminal (L) on the flasher.

At the tail light

  1. The white/black wire with the 4 mm male bullet terminal is connected to the right rear turn signal.
  2. The yellow/black wire with the 4 mm male bullet terminal is connected to the left rear turn signal.

Right handlebar switch

Applicable to these part numbers:

IMPORTANT NOTE: It is very easy to destroy original or aftermarket switches when using a conventional soldering iron. Even if you know exactly what you are doing and are very experienced with soldering procedures, the switches can very easily be rendered useless. Rather than using solder, I strongly recommend the following:

Connections at the front of a modern replacement (non-original) solder required switch as sold by MG Cycle.

The wires from the right handlebar switch (purple, white/black, yellow/black) are routed along the handlebar, down past the right side of the steering neck, to under the fuel tank in the space provided by the frame.

  1. The white/black wire with the 6.3 mm female spade terminal is connected to the 3 connection female spade connector distributing current to the right turn signal circuit.
  2. The yellow/black wire with the 6.3 mm female spade terminal is connected to the 3 connection female spade connector distributing current to the left turn signal circuit.
  3. The purple wire with the 4 mm male bullet terminal is connected to the purple wire with the 4 mm female bullet terminal from the turn signal sub-harness.

Front turn signal extensions

Applicable to these part numbers:

The extensions are routed from each turn signal, along either side of the steering neck, to under the fuel tank in the space provided by the frame.

  1. After you have routed all of the wires, have test fit the fuel tank, and know precisely the length you need, connect the extension wires to the turn signal wires. Please plan carefully, too much length is nearly as bad as not enough.
    1. Cut the provided extension wires to length.
    2. Cut the provided sheathing to length.
    3. Slide the sheathing over the extension wires.
    4. Slide the provided heat shrink over the extensions.
    5. Strip the insulation from the end of the extension wire.
    6. Strip the insulation from the end of the turn signal wire.
    7. Crimp the striped ends together using the provided butt crimp.
    8. Slide the heat shrink over the butt crimp and shrink it.
    9. Slide the sheathing over the finished assembly.
  2. The white/black wire with the 6.3 mm female spade terminal is connected to the 3 connection female spade connector distributing current to the right turn signal circuit.
  3. The yellow/black wire with the 6.3 mm female spade terminal is connected to the 3 connection female spade connector distributing current to the left turn signal circuit.

Rear turn signal extensions

Applicable to these part numbers:

The extensions are routed from each turn signal to the tail light.

  1. After you have routed all of the wires and know precisely the length you need, connect the extension wires to the turn signal wires. Please plan carefully, too much length is nearly as bad as not enough.
    1. Cut the provided extension wires to length.
    2. Cut the provided sheathing to length.
    3. Slide the sheathing over the extension wires.
    4. Slide the provided heat shrink over the extensions.
    5. Strip the insulation from the end of the extension wire.
    6. Strip the insulation from the end of the turn signal wire.
    7. Crimp the striped ends together using the provided butt crimp.
    8. Slide the heat shrink over the butt crimp and shrink it.
    9. Slide the sheathing over the finished assembly.
  2. The white/black wire with the 6.3 mm female spade terminal is connected to the 3 connection female spade connector distributing current to the right turn signal circuit.
  3. The yellow/black wire with the 6.3 mm female spade terminal is connected to the 3 connection female spade connector distributing current to the left turn signal circuit.
