Further info. I am sure others will chime in, and confirm this, but just so you know... one of the small terminals on the solenoid is the "I" terminal (spade terminal), it is the one closest to you, and comes from the ignition, while the other small one (spade terminal) is the "S" terminal, which goes to the starter. The large terminal closest to you is for the positive wire from the battery, while the other large terminal goes to the starter.
