Yo guys, they're are two spots on the rear of my si manifold, 88-91 of course. The both of them look like hoses spot or locations of some sort. Anyways i can't seem to figure out where they go, so some pics of the rear with the hoses hooked up to see where they go is appreciated. Will take left back shots or right back shots also, basically anything that shows where those 2 go too.

 

I use to know where they go but i forgot, i haven't had D series in so looooonngg...

 

Bump, im having trouble finding some, so i din't know if anyone had some they could post up.

 

Nobody ever answers my threads, i guess people can't read or they just flat out too lazy, or both.

 

i need more info to help you out it could be the brake booster hose it could be a spot that just need to caped off. also the locations of the where you think the hoses go would be helpful . ex top left bottom right and so on

 

this is 89-91 Si - 88 doesn't have Fast Idle Control on manifold - it is on the firewall

 

Well thanks for the vacuum diagram, but im thinkin my fast idle solenoid is missing!. Anyways the hose ports on the back of the manifold next to the EVAC or IVAC, or wtf eva it is, they are like this | | So im thinkin of of them go to the skinny port third to the right of the thermo housing.

 

The other one idk where the fudge that goes.
