It wasn't too difficult although I the probe for the EGT isn't in the exhaust manifold yet, the local garage is soldering a nut on for me on Tuesday.
I plumbed into the turbo lines near the intake manifold for the boost gauge as per pics.
Installing the gauges was fairly easy, they are held onto the dash with double sided tape and are fairly secure. I drilled a couple of holes from underneath for the wires. I hacked into some wiring behind the dash but didn't bother hooking up the dimmer feature as they aren't too bright anyway.
Boost maxed out at 10psi. After christmas I might find a tuner down this way to increase the boost and fuel a bit and see how we go.
