Yeah, You're right on the position of the solenoid, and you hook the side large post to the hot post of the battery with large cable, and the large post on other side of solenoid to the starter with the large cable. The single wire that comes from the starter switch goes on the small post to the front, and if theres a second small post, it doesn't have to nave a wire on it, but normally it is a power cutout to other things that are not needed to be powered when cranking. Use a test light and have someone crank the engine over to test and see for sure which wire is the one coming from the switch before you connect it.
