No problem with the videos. I previously read about the location of the relay here:

and once you find it (didn't do it myself yet, but it appears to be the first relay on the passenger side, fuse box in the engine.) it should have a Hella logo. i have searched for the original post with the hella pict, but can't find it. I had saved it on my pc, it for future reference so here goes - but not mine!
