I have recently acquired a F.A.S.T. XIM and harness to use with my XFI 2.0 on my 512 big block 1967 Dodge Dart GT convertible "Home-Brewed" to convert it to Coil Near Plug. I have made my own adapter to use a 4.0L Jeep Cam Position sensor. I have also had a steel 36 -1 Trigger wheel made and have made my own adapter to mount it to a March Serpentine crank pulley. I have a MSD 4 magnet trigger wheel. It will not work with my harmonic balancer and March Serpentine crank pulley. The pulley is moved out 5/8". I do not want to space my water pump pulley out that far for fear of putting too much load on the bearings. I am using an MSD crank trigger sensor mount. I would like to know if anyone can recommend a reasonably priced Hall Effect Sensor for use with the Ferrous (steel) trigger wheel that can be mounted in the MSD bracket. Also when setting the XIM DIP switches. Will I set them 1 - 1 - 0 - 1 Ford Mod, 3 Valve* 36-1 (5 tooth cam)? I have the missing tooth at TDC and the sensor set on the fifth tooth Can the XIM harness wiring to the coils be ran in the same firewall gorment as the XFI wiring? I am "Rebuilding" the XIM harness per the 301312 harness schematic for use with GM coils. I also need to know where to pickup the Tach signal to use with my Aeromotive Fuel Pump Speed Controller.
