TOPGUN UNDERTAIL WIRING

[GABusa73]

Just got a topgun undertail for my 04 busa. The stock plug has white/black stripe, black/white stripe, and brown wires. Topgun has black, red, and yellow wires. Does anyone know which wires I'm supposed to connect. Any help is greatly appreciated.

I found out that the black wire on the undertail is the ground, red is brake, and yellow is running light. I don't have my manual any longer can any one tell me which wires are which on the stock plug - brown, white w/ black stripe and black w/ white stripe wires?

the best way i know of right now is take a test light a figure each wire out,if you dont find out i will take mine apart and look for you.
