EFI Conversion
My blue wire goes to the tach output wire from my MSD 6AL. I have electric fans but I don't have the FiTech controlling them so I can't help you there.
My white wire goes to the ballast resistor.
I kept my setup as simple as I could. No fan control or timing control. My timing is being controlled by the MSD setup very well so I didn't want to mess with it.
