electric fan question?

[sli240sx]

I have a E-fan question. I already own and have installed a dual 12" flex-a-lite puller fan. But I purchased the cheaper model with out the Temp. Sensor & A/C Relay. I was wondering if it would be possible to some how purchase the temp. sensor and a/c relay and install them with the fans I currently own? Because right now may fans are constantly on. If you guys could and anwser this question it would help me out a lot. thanks

a little expensive, buit this is the shizzle.pivot for a cheaper option you can pick one up at your local dumbestic hotrod shop for a little cheaper, just looks like a GM engineer went to work under your hood.summitracing
