i have an 83 turbo efi harness,83 turbo engine. it's now in a 83 non turbo zx. the white wire from the water tempiture switch is for the aux. cooling fan. it attaches by the battery into the connector. the white wire is an extra wire! where does it splice? I have done the home work and still can't figure it out. Someone must have had the same situation. Anyone who can help i'll truly be in debt too. Steve
