Still having problems (electrical)

[99owned]

So, In my other post.... I got the suggestion - key switch for the fuse holders and headlights coming on with the connection of a battery to my Tank Touring 250.. Now, I don't think it's the key switch, because if I don't even have the key switch connected or on for that matter it will still activate the headlights when I connect a battery. I have used a test light and so far, I've gotten to a brown wire in the tail lights some where.....?>????? This is really messing with me xD. Any suggestions?
