I'd vouch for a 5. Mishimoto has been solid and clean cut in my experience. Of the available options I saw looking for fan controllers, this set appeared to be the most complete and straight-forward. Haven't done an install yet, will update, but first!
I got this controller to help me with an old GM 3.1 60° V6. Not sure if this was an issue in later variants, but in my vehicle the fan dont kick on til the temp gauge hits around 220-230. Not *cool*. Secondary fan only operates when the air conditioner is running.
Since this system is stand-alone I can leave the stock sensors in and just rewire the fans to this controller, make use of both of them. Hiccup though. 5/8 NPT thread for the temp sender on this engine, and for the life of me I couldn't find a way to adapt from this 3/8 up. Mishimoto just so happens to provide an adapter (also on amazon, separately, but only ~$25) which works with this controller's threaded fitting (didnt dig the idea of pushing one between radiator fins.) Its an inline nipple type fitting that gets cut into the radiator's inlet hose. So, its really getting me out of a pickle here. Really makes this option pretty universal when paired.
