Remove Engine cover by unscrewing screws, they will pop as soon as you twist them slightly.

This is the Fuel Pressure Regulator, this is where you will tap the boost gauge into.

Cut the tubing.

Connect the T-Valve (I bought this one from a local pet store because the auto parts shop was closed).

Connect the tubing all together.

Neatly run the tubing to the firewall attach it along the way with zip ties.

This is where we are going to enter through the firewall, VW was kind enough to leave this spot open for us.

Just poke a small hole into the grommet and slide the tubing through.

You must remove the panels to gain access to the wires, first remove the fuse box panel.

Next remove the bottom panels.

Grab the tubing entering through the firewall and pull all the slack into the car.

The following steps are dependent on the location of the gauge, I'm going to be installing mine in the storage bin above the radio, so I needed to first loosen the radio from its sleeve (I used the VW radio removal tools, but you can use a Jig saw blade) then I removed the storage bin.

Run the tubing through to the desired location.

Next we need to hook up the lighting wires, I taped into the dimmer switch all you need to do is run the power wires behind the dash much the same way the tubing is running and all the way to the dimmer switch, from there you can tap into the two end wires, I just pushed the wires in and taped everything up.

Hook up the coupling for the tubing, tighten everything up.

Tighten both the coupling and power wires to the gauge.

And that's it, your done, this is the reading you see when you first turn the car on and are running it stock, I'm not sure what the reading should be for a chipped car, but once you test the gauge out I got a stock boost reading between 7-9psi.
