I was looking for a wire to tap into to feed a switched relay . I have now got a CD containing a PDF of the Service manual and have identified a brown wire as the brake switch feed and I have tapped into that.
As for the TDM forum it seems to be sparsely populated with almost no community derived information such can be found on here about the Strom. I am not enthused by the dire layout and thin content the fact that many 'recent' posts date back to 2006. And finally, the teasing request for cash in order to have "extra content" become available. It's not the money as much as not wanting to "pay for a pig in a poke".
