Boost Gauge Install Problem

[Up_Troys_Bucket]

Hi,

Trying to install a boost gauge in my 89 R32 GTR. I've searched the forums and Google extensively and there is a lot of great information about teeing into the stock boost gauge line as shown in the attached picture borrowed from a diy thread on this forum. 

Problem is that line has been removed on my car. There are some other diagrams but I'll be honest, I don't get it. 

As I am a simple person and visual learner, does anyone have or can anyone take a photo showing me where that line used to connect to the engine? 

That way I figure I can skip teeing into that line and just connect the tube directly to the engine. 

Thankyou in advance!!

There's a little vacuum manifold that connects to all the inlet runners between the throttle blades and the head.  This is where the 26 gets vacuum signal to run the brakes, and boost gauge, etc.  You will not have fun trying to work under there.

I'll be honest I don't understand any of that. Don't get me wrong, I'm solid with wiring and connections and diy maintenance I just don't understand the parts and where they are but it sounds like you're saying it's a PITA. 

Engine bay is pretty chokers, any other suggestions?

Where your fuel rail is, you can see the injectors.  Where they enter the inlet manifold runners is the spot where the vacuum signal comes from.  But the vacuum manifold I described is UNDER the inlet.  If the hose is not still present and just blocked off, it is going to be difficult.

Go the easy slightly bodgy option, tee into fuel pressure regulator signal. Make sure it doesn't come off.

Thanks for the help guys, still not getting it. 

All good, I'll just have to take in to someone ??
