Vacuum line help

[SplotchyAphid05]

I appreciate all the help on my previous posts and hopefully this is the last one before i can show off my little project truck to the page but i cant for the life of me find where all the lines go and what line i need to replace so if anyone has pictures of the routing and i diagram that would be greatly appreciated also it is a 1990

i think ive figured them all out except for these two hoses that come off of the intake manifold so if anyone has a guess where they might go im down to clown with some ideas lol

There should be a sticker on the cores support showing a diagram. Assuming it's still there.

So it has one but it doesn’t show where those two hose nipples attach to

Going from memory, the ones on the intake manifold (so after the throttle body, which has two vacuum ports as well, on my '90 BII) go to the brake booster, the automatic transmission (if applicable) and the cruise control.

Hi,

Here is quite good explanation of all the vacuum lines in 2.9.

I just watched that video, pretty good. Then I look at the comments and had a senior moment, turns out I watched it (and commented on it) probably a few years ago...
