   I'm going to be wiring a EC3 as soon as I get my order from Tracy.

 I hope I do not still need to wire it.
 Yes, I had to wire it more than once.  I can't really blame that on the
 unit though....it was more my learning how to wire from scratch and the
 long runs of a larger canard.

Hello Paul

I did an EC3 with success not to long ago;
Things to watch for are:
Coils pin labeling (easy to mix up)
Also watch for data wiring between AQM and EC3 (easy to mix up data in and
data out direction)
I prepared the EC3 harness leaving wires longer than needed and group them
together by end location:
(coils together, injectors together, EM3, AQM, power etc.. then routed each
group terminating them at their respective ends.
I bought connectors with pig tails for the injectors and LS1 connectors for
the coils, it makes it easier, cleaner and quicker to do I thing.
Proper tools for stripping, soldering, crimping are required and a schematic
knowledge is mandatory I thing specially for grounding and shielding.

But the EM3 screen and software helps a lot in troubleshooting afterwards.

After all apparatus were sitting in the right places, building, routing and
terminating the hardness took over 50 hours.
Testing and verification took about 8 shots of one hour mainly reading up
manuals
Engine started on first attempt.
