  4. Connect only Green wire to brake/tail lamp wire. This activates brake light during engine braking.
  5. Insulate the remaining Yellow wire, either with tape or with posi-tap connector
  6. Device can be mounted upside-down to disable flash mode.

Advanced Installation (Emergency Brake Flash Mode)
