Let me lay out some circumstances for those of you who may or may not have ever attempted to put an aftermarket rear brake light on your cb1100:
You have a Green/yellow wire, a Black/brown wire, and a Green wire.
The brake light has a Red wire and a Black wire.
So, the goal is to figure out which two wires attach to the Black and Red wires and which one is left unattached (the ground). Of course, we don't live in a world where wire colors make any sense or live by any form of consistency, so i thought "trial and error right?" wrong. I've now blown two fuses, i think i've tried every possible color combination in the universe, and I still can't figure out why this won't work.
The best result i've gotten and the only thing close to success: When attaching the green wire to the black and the Green/yellow wire to the Red, the brake switch activates and the light comes on. I've taken the red cover off so I can see the actual bulb filament ignite.
When I swap these wires to their opposite positions, the brake flasher switch STILL works in the exact same manner, and the same bulb filament ignites.
I have never succeeded in getting the bulb to light up when the black/brown wire is attached at any position.
The bulb, upon visual inspection, appears to be in perfect working order, both filaments.
