you know those times when the car really does your head in .

I've reassembled the dash to find that my fog light comes on only with dip and flash, not with main.

Is there anywhere i can take a feed which is live during dip/main/flash but not sidelights?

Its all academic anyway as I can't prove my engine age so he'll refuse to put me through a passable emissions test.

You've probably got the same sierra stalks as I do, easiest thing for me was to take a parallel feed from the main beam filaments to the fog switch, but fit 2 diodes, 1 into each feed so they dont back feed the other set of filaments when they change over. Works on mine, diodes were maplin code uk59p
