If I may chime in here if your ignition controller has trigger outputs =
so as to put out one output for each coil then you can use the triggers =
from the ignition controller otherwise you will need some type of =
ignition controller to take the single trigger and register it for each =
coil separately and send the trigger to that coil when timing is right.

  Subject: Honda Direct Fire Coils

  All this talk of wasted spark coil packs got me thinking.  I am =
thinking of trying to use Honda direct fire coils from an S2000 on my =
race car (Honda 4 cyl, 10,000 RPM)  They look like a long (6") spark =
plug boot (if anyone hasn't seen them) and sit directly on the spark =
plug.  They also have a built in ignitor.  The only terminals they have =
is +,-, trigger and of course the connection to the plug.  No idea what =
kind of trigger input it is looking for, the service manual has =
absolutely nothing.  I need to figure out if I can fire this with a =
Haltech IG6. =20
  =20
  Anybody have any info on these types of coils?  I would really like to =
be able to use them as having no plug wires means there is four less =
cheap parts that can break and end a race (same reason why you wont find =
a single fuse in the car, and before someone asks, yes, that includes =
any computer fuses)
