I put four Hella FF300's driving lights on my new rack last December. I also have a Hella work lamp on the back of the rack. I ran the wiring up the front A-pillar with a six wire connector in the driver's door jamb, if I need to remove the rack.
I have converted to coils springs from the electronic air suspension (EAS), so the EAS switches were useless. I removed the EAS switches and surround from the dash. I replaced them with the Discovery switch surround with two fog lamp swithces (green light) and one driving light switch (orange light), and three switch plug-in harnesses (with lead wires) that I got from a Land Rover salvage yard. This set-up plugs right into the dash on 1995 Range Rovers. I got the idea to use these switches by comparing the switch surround in my wife?s 1998 Discovery to the EAS switch surround on my 1995 Range Rover. I wired the lights to these switches and I also wired the dash lights to these switches. It is a very clean installation. I showed it to John Lee and Ho Chung of Expedition Exchange in at Truckhaven in January. Recently, they started selling the surround and switches in the Land Rover Genuine Parts section. I recommend getting the plug-in harnesses for the switches. It just makes the installation so much easier.
A year and a half ago I removed my airdam and fog lights. I got light clips that clamp to the top side of the front bumper. I mounted my original fog lights and hooked directly without having to rewire. The only thing that I had to do was flip the fog lamp lenses so the "top" marking was in the right location. Also, fog lamps are meant to be mounted to the lower part of the vehicle, if you go by the manufacturers installation instructions.
Hope this helps
