Dual Electric Fan Wiring Kit - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a dual electric fan off of a 97 3.8l Camaro. They are almost identical to the lt1/ls1 fans. I was looking at the wiring kits and noticed that there are different ones for single and dual fans. Which one do you recomend for dual fans without spending a fortune? Also should I set it up so that both fans come on at once? Thread in sensor or radiator probe?

BTW, I read here that both the fans combined pull 57 amps on start-up and 13.6 amps afterwards. Didn't know if that would influence what kit was needed. I would just use the one in the article but the price is kinda higher than I was looking to spend.

Wire each fan with seperate relays. The only common connections shoud be two. One IGN source to each relay. Tie the relay inputs (on) together down to the head probe. Use a fuse between the battery and the relay. I use the 30 amps fuses. The fuses have two little nuts on them.

The head probe replaces the adjustable theremostat. The high and low side to each fan. Tie the 85 connections together. You can ground them any way you like.
