i am going to fit a boost gauge on a 99 wrx ra,were will i attach pipe onto so to get a correct reading for my gauge

 

Any small pipe off the mainfold, just unplug and stick a tee in.

You don't need to T into any pipes. on the manifold where the existing thin gray vacuum pipe is located there is another port that has a rubber bung on it, just pull off the bung and plug into that, keep the rubber bung for safe keeping in case you need to remove the boost guage pipe, you will need to replace the small bung if you do this.
