    just a few general questions about these:

    1. what do they do exactly?

    2. what's the difference between them?

    3. if i have a 4-port, does that affect what type of plow i can hook up?

    Nope, just have to have the right control harness and the plow wiring has to match, i.e., 2 plug harness or 3 plug harness.
