I was looking at configuring relay port #1 to turn on a couple small 12v computer type fans for cooling the electrical bay based on the temp from a probe. That looked fairly simple and I configured it. But when I looked into hooking up the wires from the fan I found what looked like a port with three connections that probably needs a special connector based on its shape. What connector is that? I will need to purchase one (or two) so I can wire them in. Also I didn't see a pinout diagram, there are three pins, Positive, Negative & ?? What is the third one for, doubt its another ground/negative. I am hoping i can buy them somewhere.. traveling in Alaska at the moment and my existing thermostat the ran the fans went kaput.
