I like this a lot. Can I pick your brain on where you tie into for drawing vacuum?I don't want to see a vacuum gauge while I'm driving (too distracting) but I do want to have one in the cab for idle diagnosis to keep an eye on the EGR valve. So I installed it out of my line of sight down near the floor. There's a threaded insert already where I installed it, so all that was required was to screw in a bolt. No drilling.
