Really simple install, two headlight plugs get swapped (pull the old one off, plug the new one in), plug one old headlight connecter into the mating connector on the harness, find two sheet metal screws near the headlights for the ground connections and hook the two power leads to the + battery clamp, alternator post or to fuses depending on how you want to set it up.

Can take as little as 5 minutes depending on how much "stuff" is in the way of the headlights, varies with model year and engine.
