More pics under the hood, I completely removed the heater case and repainted it as well. I also took the time to apply reflective heat insulation on the inside of the case and apply some stainless steel accent pieces.
I had debated on locations for the ECU and it basically came down to where the harness would reach... so I built a bracket and bolted it to the inner fender well. I used some windshield wiper motor mounting bushings (say that fast) to insulate the ECU from grounding out.
