vz vacuum line for gauges

[dvsride]

Sorry i feel like a bit of a slow for asking but i cant find the vacuum line to connect a vacuum gauge to? can anyone help me at all? i have a 2004 vz sv6

theres a couple of barbs at the back of the manifold, find the one that supplys vacuum to the hvac unit, buy a t-piece and fit it into that, i wouldn't touch the brake master cylinder hose, thats a big safety issue if something goes wrong
