Default Vacuum/Boost Gauge Install

I've searched a lot for this. Maybe, I'm using the wrong key words. Anyway, I own a 2002 WRX. I just bought and want to install an Autometer boost/vacuum gauge. The instructions say if it were just a boost gauge I could install it using a T-fitting, but since I have boost/vacuum I need to hook an 1/8" adapter into the ENGINE PRESSURE PORT. I have been unable to find out what this is let alone where it is on my engine. I showed my car to a talented mechanic and he couldn't find it, only said that it should be somewhere on the intake. Could someone please link me to a pic or diagram or install instructions showing where the engine pressure port is or some other really easy way to install this thing. I would greatly appreciate it. Thanks. Oh yeah, is it possible that I might have to remove my intercooler to access the preesure port? Just a thought. I could really use some help.

Thank you for taking the time to post a picture and help me out, but the Autometer instructions say to tap where you showed in the pic for only a boost gauge and that for a vacuum/boost gauge you need to tap somewhere into the engine pressure port on the intake system using a 1/8" adapter that they provide with the kit. So, I'm not sure if that location works. Arghhh!

Probably the alternative location is given for people fitting it as a vacuum gauge on a naturally aspirated engine. You for sure will be able to read vacuum from the location posted by 02redwagone.

if the 1/8 doesn't work. i found a 3/16th one you can get at autozone works better, the firewall plug you run this through is behind the intercooler
