It was really simple. One of the other threads has a write up. Remove the windshield, plastic behind the windshield and the 4 bolts holding the headlight assembly in. Pull the headlight out enough to remove the bulbs.
The part number for the lights is on the box in the picture. As far as wiring, I bought the road shock wiring kit at harbor freight. It was $20 and had wire, solenoid and water proof switch. I had to shorten the wires a lot to make it fit.
