Thanks a lot for your pix. Especially appreciate pic #10, as after my wife's 2001 Legacy was hard to start, I took it to the diagnostics and they said that I have to replace 'barometric pressure sensor'. Will look into it closer tonight... By the way, if someone needs, the OE part # for that sensor is 22626AA000. As I called the dealer to get a quote, though $350+ is way too much for the piece. So I guess I will go with the aftermarket one (https://www.carid.com/barometric-pressure-sensors/). Hopefully, it will work...
