Make sure the wires are protected and do not cut when you refit the tray:Ĭonnect the battery. I used the centre tray to rest the guage inside it:ĭouble tape the gauge onto the tray and run the wires under it by running just over the edge. I wanted a place high enough but not in direct vision as it can be very distracting. Splice into the wire and solder the wires gently on to the required wires:įind a place to fit you guage. NB!!: disconnect the battery as you will now prepare to solder. Do not cut any wires!! Use a volt meter to see which wire you need. The best way to get these and the most unobtrusive way is from behind the radio. My gauge doubled up as a volt meter so i needed power from the key, power from the battery and an earth wire.

You will need to remove the boost pipe for this by removing the engine cover and unclipping the steel clasps at each end of the boost pipe. You can always fill gently to make the valve fit tight and to create its own thread: Make sure you leave a nice path for the pipe to run to the boost guage. Drill where the connector will not rub against either the engine cover or the water botle.
Practice drilling on an old pipe 1st using a drill slightly smaller than needed. Prepare the valve by removing the inner valve by cutting the copper part: I used a cheap but logically sensible bicycle tube valve as the connection: I am sure the boost pipe is expensive and there is a lot a pressure there so there is no room for error and one must ensure an air tight and strong connection.
#BEST BOOST GAUGE FOR B6 A4 HOW TO#
The most important area point is how to connect the pipe from the boost sensor to the boost pipe. I have highlighted some points to be careful of, but the list is not comprehensive. Firstly, this is a DIY installation and i am not a qualified mechanic so every thing you do is at your own risk.
