The sensor is either a screw in type that goes into an engine coolant passage, OR a long probe style that inserts into the radiator fins to sense radiator temperature.

The relays exist to route positive current directly from the battery posts to each fan (by activating the relay).

Google is your friend. I just typed "fan relay wiring" and came up with this article and about a billion more:

Start Googling and teach yourself how to do it. Not complicated, just understand positive and negative functions and how a relay works.

As Mr D said, it is simple however, that's after you understand it. Do a search for sure but I will put it in words for you just I case you can learn that way. If you can post a pic or a link to the kit that you got it will help with that if you didn't figure it out on the line.

Given that it's a dual fan set up you either got two separate relays and either separate temp sensors (screw in or bulb for the radiator) or you got a kit with a fan controller. In either case post what you got and we can put words for how too. And not too as well.
