i purchased the flx60 efan for my blazer and wired it up. when i turn the ignition off the car stays on and so does the fan. i hafta disconnect the battery to get the car and fan to shut off. i have an msd ignition and am wondering if i possibly need to intall a diode somewhere. it almost seems like it creates a loop. if i dont hook up my ignition controlled wire and wait for the car to hit temp and then touch it to the battery it turns on, but still does not turn off when i turn the car off. any suggestion anyone could give me would be great. unless its telling me im a moron and to put the stock fan back on.
