There are only 3 connections. The Red lead goes on the positive terminal. This is the biggest one and is more outboard. Some alternators have a stud connection that's red inside, under a rubber ''hood.'' The field connector is a dual-lead plug that snaps in to the socket at 12'o'clock on the back of the case. The Ground stud is more inboard and connected by a smaller Black lead, sometimes there's a metal clamp crimped around the whole bundle with a tab that goes into a slot on the back of the Delcotron casing. It's secured by a smaller nut.
