Not trying to knock your fine work but can I offer a couple of suggestions?
When on the power tour this year, we idled in traffic at least 3-1/2 of the 8 hours on day 2. It was HOT. The engine was HOT. The dipstick handle could burn your fingers.
Even though the cooling system kept my engine below 200 (I run a 192 degree thermostat) Everything under the closed hood was HOT. I'm afraid that one or two of your coils will cook either running or after shutting of the car, then you can't just throw another one on quickly. I have a Quad-4 that kills coils but they can be changed under the head cover.
Also that EDIS controller connector "should" be water proof. but when I get stuck in a rainstorm driving 70 mph, that area is might as well be under water. Ford ALWAYS mounted those high.
Okay, I'll shut up now. Thanks for your help on that'81 fuel injected Chrysler Imperial. All of the modules melted the potting goo out of the backs because of the heat so I just put a carb on it and sent him on his way.
