Thunderbird Lt Brake Wiring

[Judagar]

I'm trying to wire a Tailblazer into my rear brake light. I really don't want to take the back wheel off, so does anyone know the color of the wire that runs the brake light from the first harness?
i found the wires running to the back of bike i need to know which color to splice into before i just go cutting them all need a triumph mechanic

Just test for the wire that has power coming through when you press the brake pedal you can do this with a simple 12v tester and a needle , just pearce each wire in turn with the needle and test for power when the rear brake is on the small tiny holes the needle makes can be rubbed over and blended back in .
