Okay so I went to install the relay kit and was looking for the wires I needed to connect it to and I realized I had no idea which was which. I took a picture of the connector coming from the radiator fan that the toggle switch is connected to, I was hoping you guys could help me out and tell me whats what.

It looks like the toggle switch just connects the black to the red (negative to positive) but I don't get how a 12v power source could be coming FROM and going TO the radiator fan.
