Itsa no brainer...just remove the short 3-4" piece of hose on the turbo itself and replace with the DawesDevice. I used one cable tie to hold the valve to the expansion tank hose. Also used an extra tie as a hose clamp on the turbo nipple(s).

I used it stock out of the box and noticed no difference in boost...apparently it's calibrated for bleed pressure. Be careful when you start screwing it in, however, because it's easy to spike the gauge off the scale (be very careful with your right foot while you're adjusting the boost) of the stock gauge and without a calibrated gauge (I've yet to install it although I have it inna box) it's easy to blow #1 connecting rod, even at 2500 rpm.

One thing I've noted is the area around the turbo pop off valve gets really filthy with oil spray/dirt. The Mitsu apparently vents to atmosphere rather than venting into the incoming air like the Bosch/Porsche hooter valves.
