One thing you could add to the “Back OFF” project is, to take a small tweezer or micro screwdriver you can back the actual clip out of the nylon wiring plug and cut the yellow wire flush with the clip. Then solder a new yellow wire to the clip install the connecter and you have a lot more sanitary end result and as much extra length in the wire coming from the plug as you want. I did this because I thought the wire was a little short otherwise.

My Best


To begin this procedure you will need 2 each, female, and 2 each male bullet connectors and a pair of wire crimpers to complete the project.

Backoff Module Wiring Diagram

  1. Remove your seat and set aside.
  2. The wiring harness for the tail lights is on the left side of the battery.
    • The Yellow wire is the Brake Light wire that you will cut and insert the Back Off module in series with.
    • The red wire of the Back Off module will plugin towards the front of the bike you will place a male bullet connector. It will be plugged into the yellow wire towards the front of the bike.
    • The Striped wire of the Module you will place a female bullet connector upon the wire and it willplug into the yellow wire going through the fender grommet.
  3. Cut the yellow wire and upon the end going into the fender place a male bullet connector.
  4. On the other end going towards the front of the bike place a female bullet connector. I took this approach so that if the module ever fails on a extended trip you could unplug the module and directly plug your brake light wires back up again.
  5. The module comes with a double backed piece of tape. Place it upon the frame under the seat.
  6. Replace the seat and go riding.
