I've heard that the proper way to wire these 2 speed fans is to have the #1 fan signal (say at 200 degrees) from the PCM trigger BOTH fans at low speed simultaneously; and then the #2 fan signal (say at 205 degrees) from the PCM trigger both fans simultaneously at high speed (rather than just trigger each fan separately).
