For a project where I'm going to try to fit my AEM FIC in the box with a custom taller lid, as the title of this question indicates, I need a new ECU box lid for my 2005 Lexus 300. Do you know if the ECU boxes or lids changed at all between 2001 and 2005? In order to make it look reasonably stock and avoid having to extend any wiring, my goal is to cut the second lid so that it would essentially stack on top of the original lid, seal it together, and shove the FIC and related wiring inside.
