The two large ones are for the battery and starter. The two smaller ones are for energizing the solinoid. You have what is called an insulated solinoid. The way that I wired mine is up is called gound seeking. I ran a wire from the battery terminal to one of the small terminals. The other terminal is run the to starter switch and the from the starter switch to ground.
Make sence?
