Default boost guage vacuum source

im in the middle of installing a boost gauge on my bird and tried searching but havent found a pic of where to tap in to a vacuum line. i know that the brake booster is an option but id rather not have to run to the store to get the right t fitting. ive read there is a vacuum source between the hvac and the engine on the passenger side but cant find that line. also is it possible to use the fitting that came with the autometer guage (mechanical)?? pics are greatly appreciated

i thought that you redid the factor vacuum lines, my bad. my lines are set up just as it rolled out of the factory.
the big black tube is the brake booster, correct?


did you make a "T" fitting or what? thanks man, i appreciate it

i redid my PCV lines which is another story.my vacuum lines are stock.i T'd the brake booster line for 1 source and T'd off that for the others.my boost gauge connects on the passenger side of the intake as you cant use the stock PCV with no checkvalve as it will pressureize the crankcase.i just took off the line goes from each valve cover and connects to the pass side of the intake and ran both valve covers to a catch can and then to the inlet on the turbo and used the port of the pass side of the intake for my boost/vacuum gauge
