I have an 2004 TB with the 5.3 in it and I just noticed this morning a rectangular box on the drivers side of the engine bay. It has Delphi written on it and a couple of hoses coming off of it. Anyone know what that is for/does?
Apologies if this is in the wrong spot, I put it here because it's close to the engine.
