The two large joints are the positive pole and ignition switch (i.e. key switch) of the battery at one end, and the output positive pole of the starter and generator at the other end. A small thin line, a black one is the negative pole (that is, the tie), and a red one is the positive pole (that is, the control line). When the key of the door is opened, the red control wire is energized and the electromagnetic switch is sucked and turned on. Then the switch can be started.
