need the switch by the electric mirror adjuster, theres a blank there and if you get a small screwdriver in it just pops out, wiring for the switch is just behind there. place for the relay is behind the dash in the area of the bonnet pull but further back, if you get on the floor you can see a few relays and a place for a relay, just plug the relay in and thats the wiring from inside the car done. wiring is there behind the bumper, clipped up out of the way, just plug that into the fog lights and thats it, fuse should already be there.
easy enough to do, few hours work for me because i was struggling to find were the relay went and spent a while trying to get part of the dash off before realising the switch just popped out and that bit of the dash doesnt come out :lol:
