NOTE: The center vent shut off controlled with the wheel on the left of the center assembly that is located on the back side of the center vent assembly needs to be removed or notched heavily for install. With any gauge install this back block off vent is best to be removed or notched to clear hoses and wires. Even if notched for the hoses and wires it can't fully seal. In our experience it is easiest to just remove it. We cover this in our instructions as well.

just installed mine and it looks FRESHHHH!! the kit includes every single little piece that you need for install and a special thanks to the AMAZING idiot-proof directions included in the package. jhm really goes the extra mile to make sure they cover every step and it shows. only down side is the price and the fact that the very bottom of the gauge doesnt illuminate as well during the day. It works great at night though. Review by jordan (Posted on 5/2/2010)
Great product, I especially love that the lighting perfectly matches the rest of the car. Installation was quite simple and took maybe 45 mins. Performs great so far. Only issues would be that the numbers for Vac don't really make sense. 0-15-30. Middle marker between 15-30 would be 22.5? Otherwise it's an excellent product from a great company and I'm more than happy. Review by Ben (Posted on 4/20/2010)
