Conversion wire group for handlebar brake light switch -BGM PRO- Vespa (-1997), Lambretta - used with brake master cylinder

To do this, screw in a brake light switch on the brake pump (if not already existing). The cable branch is pre-fabricated to be connected directly (incl. rubber seal).
Lead the cables through the steering head and the inside of the frame to the brake pedal and connect them parallel to the existing cables of the brake light switch.

To do this, remove the cable lugs on the original vehicle wiring harness.
Join the loose cable ends on each side and reattach them to the brake light switch with the enclosed cable lugs.
