FiTech EFI system

By the way, in the initial setup there are settings for "Tach or VR Coil". If you are using the blue wire from the Fitech to the negative side of the coil then you MUST set it to tach. If you are controlling the timing using the MSD distributor then you connect the 2 wire connector from the Fitech to the matching 2 wire connector from the distributor. Use the small black wire to trigger the MSD. This should connect to the points trigger input to the MSD (typically a small white wire). Again if you don't select the correct trigger (Tach or VR Coil) shesa nota going toa strarta.LOL
