MY99 Uk Turbo Boost gauge install
Installing my Defi tomorrow but where do I connect the rubber hose on my model? I've read there's a certain place on the 99/00 models?
Any pictures?

The rubber vac hose goes direct to the manifold - if you happen to have a spare unused nipple available (if so it'll be covered with a removable cap).
But it's more likely that there won't be one... So the thing to do is locate the vac feed for the dump valve (the brass coloured round thing attached to the passenger side end of the TMIC). Then you can cut that length of hose in two, and rejoin with a plastic T-piece of suitable size. Then, using the T-piece's remaining 90-degree port, plumb the boost gauge's vac hose to it. Then feed the vac hose through a suitable rubber grommeted hole in the firewall/bulkhead and on to the rear of the boost gauge...

Joz if its a 99/00 uk car it will definetley have one and its easy to find.
As you lift your bonnet up,look where your alternator is at the front of the car.There is the main power lead going to the alternator which normally has a red cap covering the lead,directly behind the lead on the right on the inlet manifold you will see the 2 vac pipes,the small one(LHS) is covered with a plastic sheath,simply pull this off and away you go,connect your 3mm tubing and run the piping to follow your existing vac pipes & job done.The other pipe goes under your coilpack to your recirc/dumpvalve if you have a tmic .It is the same on all V5/6 wrx's iirc,as they have 3 vac pipes on the inlet manifold where the earlier classics only had 2.

Cool thanks

Most normal gauges just connect into the back of the gauge,i forgot defi's were different.You do not need to take the intercooler off just to fit the boost gauge,simply connect your sender to the pipe and secure it either at the back of the coil pack,or a nearby location.

Cheers midnight.... I should have known that, as I have a STi 5!!! 
I just assumed the OP's one would already be in use (say, something attached to it by a previous owner). lol
And yeah, my vac hoses are hooked up exactly as you say.
Where's the 3rd small nipple (on the RHS) go to? It surely goes to the BCS's PES, right?

Did you install it there or someone do it for you? Considered this myself but the cup holder is more use than the ashtray...

.The RHS pipe goes into a t piece which has one pipe going to the bottom of the bcs(map solenoid) & the other to the black circular valve under your air filter inlet hose.

I wanted the thing to be visible, and it is.
The only thing I have against it is that the little LED that Defi provide to tell you when your boost gauge is linked to your fuel pressure gauge, so as to show DIFFERENTIAL fuel pressure, is RED, not green.
It does make me wonder, and you'd be surprised at the number of folk I've had in who've said, "You've got a red light on here mate..."
Had there BEEN a cupholder there, mine might be somewhere else now, but oh no, that was one of the things Subaru took off before selling cars to us at higher prices:mad;
Along with better seats, better engines, better gearboxes, better headunits, better lights, rear wash wipes, folding mirrors......
