Engine 1989 5.0 Where to install tube for vacuum gauge

[1989LXFOX]

Hey everyone,

I bought a glowshift vacuum gauge. I have everything else installed I just need to connect the provided tube a vacuum tube. The directions just say splice it into any vacuum line. I would ideally like to do it close to the tree. Does anyone have a good idea which vacuum line I should splice it into and where it is? Btw this isn’t for boost or anything, just a vacuum gauge.

Thanks in advance!

Is there a unused connection on the vacuum tree? You can t it off any same size vacuum line, I would not use the purge canister line or fuel pump regulator.
