I am not familiar with your Fans but to the best of my knowledge each fan will have a ground wire and a hot wire The ECM has fan one and fan too in order to have high speed low-speed you need three relays fan 1 for low-speed both fans are wired in series to give you 6 V for low speed When fan 2 comes on you get 12 V to both fans if you search back to the previous page there was a thread On this very subject with wiring diagram Hope it helps
