E30 Zone

hi guys can any body tell me which relay to buy for the fog lights on a e30 320.i tried typing fog light relay on ebay and nothing came up.ive changed the bulbs on the fogs and they still dont work

It's a standard 5 pin double pole type for UK spec. E30's, but your problem is unlikely to be the relay, if the correct type is present!
Pull out the relay, and use wire links to join together pin 30 and both pin 87s of it's base.
Do the lights come on (including the dash tell tale)?
