Is the 200, on or off temp? Since the PCM supplies ground, and the way you describe it working, you're going to find it's the PCM that's keeping them on, if your wire from the PCM was shorted to ground, it would make the fans stay on, but they would be on all the time, even with the key off. Did you try running it down the road to see if they go off at speed?
