Fitech Wiring Issues

The blue wire from the Fitech needs to be connected to either the negative side of the coil, the tach output wire from your CDI box (if you're using one) or the tach connection on your ready to run distributor. This is where the Fitech gets it's signal to fire the plugs. When using the blue wire you should have selected the tach option in your initial setup. If you're running timing control then the blue wire isn't used and instead you should be using the green and purple wires connected to the 2 pin pigtail connector on your distributor. When using the 2 pin pigtail you should select the VR coil option in the initial setup. Selecting the incorrect option will keep the car from starting. In fact it's a great anti theft feature. I set mine to tach and then take the controller with me. I hope this helps. I have the 600 hp power adder on my Dart
