I just purchased a 2021 Edge Titanium and the under dash fuse panel is darned near impossible to get at. There is a lot of stuff packed under there and I can maybe touch it with two fingers, neither of them the thumb. This post got me to thinking that I could use the OBDI plug to get the switchable power. If one of the connections is switchable, I'd easily sacrifice an old code reader to cut off the plug and wire into it. Does that sound reasonable? I'll research the plug in the time being to see what I can find.
