I bought a set dual fan setup from the local pull a part. It came off a late 90's Ford windstar van with the 3.8l. I also got a relay setup from a 90's volvo 850 or something like that. My question is the relay I have will turn in each fan individually, but will not let them run together. I want to get a fan controller but not for sure which one to get and don't want to spend a ton of money for it. I want the one with the sensor and not the one that sticks in the radiator. The fans are dual speed but each fan only have two wires and not 3. Anyone have any insight on this anyone ever used this fan setup. Also how do you post pictures it keeps telling me the file is too large
