Gary, easiest thing to do is buy the Hella complete wiring harness spec'ed for the wattage you will run in lights. Theses come complete with instructions and color coded wires to make life easy. The only thin you may find is you will have to lengthen the power and ground wires going to the lights on your rack. This is easy to do, just buy some wire length, electrical tape and heat shrink butt connectors (crimpable).
Each relay'ed harness will operate two lamps.
If you want to get fancy, you could get a Defender aux lamp switch and use that. It won't really change your setup.
