OBEY YOUR MAZDA
You can't fire the Trailing at the same time.
One will fire as it should and the other will fire simoultaneously(sp) but in mid compression
*EDIT*
Doh - note to self:

I just recently hooked DLIDFIS using two 2nd generation trailing coils, and one stock coil. Not sure if the "trick" will work but this system works fine using three GM ignition modules.

i wish some one would post a pic of a 1980 dizzy explaining which wires to use for leading and trailing. i want to cut the wires near the dizzy so i can use quick connects so i can go back to stock if one igniter burns out on me. iam little confused about wiring as is lol. my buddy who went to uti for this stuff told me to find out which wire are for leading which are for trailing and hed have it wired up in 15min's.
i all ready made a rotor shape plate to hold 2 msd blaster coils. made the plate for the 3 igniter's and have all the wire and connectors i need.

i just wanna use it for the leading side. using the the 12a igniters, just like the write-up says , but with the trailing coil instead of the leading coil from a 2nd gen.

The trailing pack is really two coils with one large ignitor. The trailing ignitor has a 'Select' line that tells which coil to charge/fire. This is normally done with the 2nd gen CAS/ECU combo. Now, if you want to use the coils, you can do DLIDFIS and use the two FC trailing coils (1 pack) as your 2 leading coils (1 per leading plug).
If you tried to wire the trailing coils in parallel and used a single stock (J-109 ignitor), I would imagine that the ignitor wouldn't last long due to the high load. In addition, I don't think you would see any performance gain this way.
If you wanted to try to use the 2nd gen traling ignitor to fire, I would say that it will not work easily as the trailing pack is designed to only charge on of the coils at a time (alternate).

I hope it wasn't my post that started all this but Wacky is correct as usual Also, GSL_SE_Addict is also correct. The way to use the 2nd generation trailing coils is to hook them up exactly as you would in DLIDFIS, with their own ignitor. I am using the bracket for the 2nd trailing coils attached to the strut tower.
