You didn't read carfully, I used Ford EDIS not VB921's.
The VB921 is a transistor that drives a coil. You can buy them from where you buy your MS kit, or from an electronics parts supplier. You need to build a simple circuit for each VB921.
Instead of VB921s you can also use any combination of "dumb" ignition modules that will total 6 output channels: 6 * single channel modules, 3 * dual channel moduels, 2 * triple channel module, 1 double and 1 quad.... etc.
You can even combine VB921s and modules as long as you end up with one output channel per coil - 6 for COP or 3 for wasted spark.
