Applicable to these part numbers:

  1. Connect the brown wire from the main harness to terminal 86 on the relay.
  2. Connect one end the short red wire (unsheathed) to terminal 30 on the relay. This end will have a 6.3 mm female spade terminal.

    1. Connect the other end of the short red wire (unsheathed) to 51B on the voltage regulator. The end will have a 6 mm ring terminal.

    Bosch voltage regulator

    1. Connect the other end of the short red wire (unsheathed) to 51B on the voltage regulator. The end will have a 9.5 mm female spade terminal.

    1. Connect the other end of the short red wire (unsheathed) to the positive terminal on the battery. The end will have a 6 mm ring terminal.
  3. Route the pair of sheathed wires to the left side of the transmission near the starter. I always route these wires between the battery tray and the rear fender in the little triangle space that is available there. I route the wires straight down behind the swing arm member, and then route them forward toward the starter area.
  4. At the relay, connect the black wire to terminal 85 on the relay.
  5. At the relay, connect the red wire to terminal 87 on the relay.
  6. At the neutral switch, connect the black wire to the neutral switch. If you connect the wire to the switch, the transmission must be in neutral in order to actuate the starter. I prefer to permanently ground the black wire to one of the bolts that secures the neutral switch to the transmission. The choice is yours.
  7. At the starter, connect red wire to the starter solenoid.
Brown wire (without the terminal on the far end) is shown here for reference - originates from the main harness.
