1983 Lincoln Mark VI have a question about the moduel

The module has 2 plugs on it, 1 in and 1 out, 1 in has 2 wires, 1 out has 4 wires, now with the key on, the plug in has 1 wire hot 1 cold, and the 1 out, has 2 wires hot and 2 wires cold, what I am trying to find out is, IS that the way it should be, or should it have 2 hot going in and 4 hot out? Thanks for your time.
