I have a 99 WR400. When I got the bike it didn't have the rear light on the fender. I removed the seat and found what I believe are the tail light wires, one blue and one black. My brake light switch has a green with yellow tracer and a brown wire. The tail light has a black, red and yellow wire. Can some one please help me figure out how to wire the brake switch in? This is probably really simple but I am having a brain fart and cant get my head around it. Any help is welcome.
