Benny,
I've never wired anything with a relay yet but there is enough info on here that I think anyone could do it.
ooooya,
When I searched your post I copied your destructions and wiring diagram and I think thats the way I'm going to do it. I like the Triumph wiring harness route but thats just more money for the same results.
Now just waiting for it to arrive and we'll see how it goes.
