Here is the pinout on the 0 221 503 407 unit:
and the 0 227 100 203 unit is pinned out as (the unit is used to run 3 sets of wasted spark cylinders):
Pin 1-#1 negative coil
Pin 2-#1 Input
Pin 3-#2 negative coil
Pin 4-ground
Pin 5-#2 Input
Pin 6-#3 negative coil
Pin 7-#3 Input
This should be the setup using these two parts:
Out From EZK: -> Into 203:____ Out From 203: -> Into 407:
1-4 output -------> Pin 2 _________ Pin 1 -------> Pin 3
2-3 output -------> Pin 7 _________ Pin 6 -------> Pin 1
Pretty picture:

I'm assuming pin 3 & 5 of the 203 unit won't be used to run any cylinders. Also, "Switched 12+", I mean 12+ when cranking too.
Karl looked it over, and thinks it looks right, but if somebody sees something wrong with it, please point it out.
