Where does this hose hook up too? (pictures)
 

Just curious to know where these hoses hook up too. Any ideas? Im swapping in a s14 SR20DET into my 1989 s13 and taking out the abs btw if that helps.

Not sure where the hose on the back of the intake manifold goes too

Second hose comes off of the brake booster... i think its a brake booster for abs? correct me if im wrong please.

take the one off the manifold and put the one from the mc on there on the silvias the mc is on the opposite side which is why it points the other way

you mean the 2 hoses in those pictures should connect together? or on a different port? thanks

yeah just take off the one on the manifold and connect the other one to it

great thanks a lot. I have 1 more line to identify for now. Not sure if you know. Its a hard line that comes from somewhere beneath the car.

It could have been connected to the activated carbon canister (i doubt it tho). Any Ideas?

yea that went to the canister i just blocked mine off with a vaccum cap

thanks for the help

brake booster vaccum should run to the intake manifold, it needs full vaccum at all times.
