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.

I'm just curious if this is the definitive correct wiring for running the setup or is this for Launch control? All the credit to Karl for the instructions, but I'm a visual guy too.

Also, if I chose to wire it this way(sans launch control), do I follow directions for the dummy coil, or for the alternate MS tach signal.

Pardon the dumb question, but where is the best switchable 12v connection for this install?

Sorry, I'm just not very electronic savvy.
