I had planned to mount the ECU up high under the dash, but am concerned with dirty/noisy interference from other components. I need to research this part of the wiring further before I start mounting stuff. Any suggestions on this would be appreciated.
I mounted my ECU under the left side of the Dash, and my Fuse Box is on the right side kick panel to isolate them a much as possible-as for RFI, I made certain that my trigger wires didn't run next to constant hots, or, I ran them at 90 degrees to each other if I couldn't-

On my ECU you are supposed to run the main power & ground (in my case I ran 8 AWG) directly to the Battery Posts (they use the Battery as a capacitor), and I ran them down the Trans Tunnel (with Ron Francis "Gray stuff"-I used this on the Driver's side also, to run my trigger wires for my Fuel Pump,, etc.)-

I too, was very concerned about interference, so anywhere that I thought there might be a problem, I used this:
