instructions are very confusing --- But wiring wise do I plug in positive or neg of the fan into the relays
A relay is just a switch. It is either open or closed, so run a positive in and come out the other side to the positive of whatever you are trying to turn on.

I have got something a little bit different to that, where it looks like 3 output terminals, but one is common, a NC and a NO connection.
I also have a plain 12v fan controller board, that like in a PC will speed up the fan as the inside of case gets warmer, which is in the case that I have my Pi, switch, and FM transmitter in, as they're on all the time.
