So I saw a lower dual fan radiator bracket, do I need anything else to switch in the dual fan?

And how would I wire it up?

 

You will also need the upper bracket....as far as the wiring goes...If you can read wiring schematics a good book is Chilton...pg. 6-58 has a 1990 5.7L tuned port wiring schematic. You will also need the wiring connections...prpbably the best bet would to find it at a junk yard...just the wiring going to the fans....Good Luck!!

 

Do you have the fans already? I have the 2 and the wires if you are interested....let me know if you are....

 

Think I've got the fans already, can take em off a friends totaled car.

 

Will you be using A/C too?
