Review on 📊 Auto Meter 5907 ES 2-1/16 inch Mechanical Vacuum/Boost Gauge with 30 in. Hg/20 PSI Range by Jonathan Olson

Haven't had time to install yet. It came with a wide range of connectors. It has two brass fittings for the vacuum line. The vacuum line doesn't seem like much, but I'll have to see how it holds up. I put a 9v battery across the terminals to see it light up. THAT'S GREAT! It perfectly matches the interior lighting of my Mazdaspeed6. TO UPDATE! It exists and works well. This is very close to what I see in my ODBII reader for Boost and RPM. The red goes well with the lights on my Mazdaspeed6. It comes with everything you need to install it on your engine. It is recommended to use a deep gauge so the line and wires come out of the capsule and the gauge is still fully seated. I bought the Autometer module (http://www.amazon.com/gp/product/B0009RUXPG/ref=oh_details_o00_s02_i01?ie=UTF8&psc=1). I had to get some 90 degree blade connectors to get the gauge into the nacelle to keep the gauge from sticking out half an inch from the pod.
