Convert your newer Hitachi D4A Distributor (A14/A15/A12) to Hall-effect using VW distributor. Only need to drill one little hole. Hall Effect is a magnetic sensor with built-in amplifier in the sensor, to create a standard voltage signal before it is sent to an ignition controller. The dizzy is locked, no mechanical advance or nothing -- the controller does that, so this is good for a custom turbo spark curve.

Overview

This can be used with an ECU or with a programmable ignition controller like MSD 6AL-2. A points distributor can also trigger ECU or controller, but the Hall Effect works reliably at RPMs in excess of 8000 RPM and need no periodic adjustment.

Modify the Golf rotor shaft by cutting a flat on one side so the Hitachi rotor will slip on. Use file and hacksaw.

The Golf's upper shaft has 2 pins underneath, where the springs get hooked up, make them fit in between the weights, and when your tighten it from the top, just add a little washer, the make sure the shaft gets tightened, so it's locked with the bottom shaft.

Install the locked contact point plate (this disables vacuum advance)
