brown, black, and double brown?????
if your bike has an a35 engine, here is a manual for it.
but if you have the a3n, you need this manual.
ive never seen a tomos engine with that wire combination. black yes, but never brown coming out of the magneto. all the a35's use black and yellow. the a3 and a3n's used black, yellow, and blue. at least on the ones ive seen.
