I have a JDM Prelude, which comes with an internal coil in the distributor. If I got an MSD Digital 6+ ignition, I'd need to get a Blaster SS external coil or something similar. How would I wire this up to an internal coil distributor??

 

Get a new MSD distributor cap for an external coil and search for the wire colors to hook up to the MSD 6 box.
