you need to cut the gray wire (or de-pin it from the connector) between the harness (white connector) and fog light relay. (this is all under the dash by the driver's knee) then take the gray wire from the relay side and tap it into the brown wires like you have already done. tape up the gray wire from the harness side if you had cut the wire. that should fix the problem with your headlights coming on with the first click.
