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.
