Thought I'd post another idea for Gen II. Coyote ECU/PCM mounting if anyone is interested.

Mounting is done with 1/4"-20 stainless screws directly into 3 nut-serts into the back of the frame at the rear of the radiator tunnel. I also used some rubber washers behind the computer to provide a little vibration dampening. The geometry works out such that you can mount the PCM directly to the frame with three screws without any sort mounting plate/bracket. You could also make a bracket and mount with all 4 screws if you wanted, but this mounting configuration is rock solid with three points. One other slight modification was to cut a notch in top engine cover to allow the PDB->PCM harness to exit— I like it because this rather large harness is now nicely hidden by the cover.
Coolant and A/C lines are not installed in these pictures, but from my mockups it looks like there won't be any interference (I'll post them later).
Quick question:
In the last picture you'll notice that I run the PDB->PCM harness leg right on top of the Engine->PCM harness leg— do you see any issue with this? I have a slight concern that high frequency noise from the injectors and spark plugs might cause noise in the harness, but I suspect the computer is fairly well hardened against electrical noise. Thoughts?
So far I'm pretty happy with this configuration, but always appreciate any feedback!
