These adapters plug into where your tail light wires connect under the seat near the rear. Power your topbox, aux brake light, etc.
Please do not except 2 Amps current takeoff if you’re powering a GPS or something low current.
Version 1 - wires are straight take-offs, not for brakelight modulators
Version 2 - for brakelight modulators, also allow aux tail lights
NOTE - version 2 has a purple wire added as input to modulator, red is output to brake light in both versions. Black is ground. Blue is tail light output.
