Boost Gauge Install Problem

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.

      [HOW-TO] Winter Steam-Clean & Odour Removal in 30 min

      Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 馃ぃ, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up
