Electric Fan Relay

[CJJ67]

I posted this question before but I still haven't gotten an answer. I'm trying to put an electric fan in my truck but I am stuck trying to correctly hook up the relay switch. I bought the grand jeep fan from the dealer and I have, what I think, is a electric fuel pump relay kit (given to me by my neighbor) from keep it clean. My question is, can I use this relay kit to hook up my electric fan. The kit is a 12V 30/40A relay, 16awg wiring, 30A circuit breaker and I purchased a thermal sensor for the 350 engine head. If I can use it, my relay numbers are 87, 86, 85 and 30. What number goes where to make this fan work. Oh yeah, my baby is a 67 stepside, short bed 350 Chevy. Thanks for any help that you can give me.
