This next one is the back of the TB (firewall side)

I know where the vaccum lines go and all .. but my question is the yellow labeled ones. Which one is the brake booster and whats the other?



Also the blue vacuum line. Is that right? Cause if it is, it kinda gets in the way of the motion of the throttle. Maybe i hooked it up wrong.

where your two blue lines end on the back of the tb i dont have anything connected to that thing, am i supposed to?



also on the last pic what is that plunger looking thing above the blue line with a screw going down onto it with a spring?



how do i tell if someone did a TB mod to my car cause im thinking that someone did. cause my tb looks nothing like that.

I went out and checked it out. It seems the plunger/screw thing really has no purpose. I was looking at the whole setup (with the screw, and where the 2 vac lines go in) and you can take it all off. However it has a gasket that looks like it will break if i take it off. So im gonna leave it on until i can find out what it is. As for not having lines connected to that plastic thing sticking out. Ive always had lines connected to them. Whatever it is, its reading pressure.



My main concern now is the nipple on the block and the 2 yellows (which ones brake and if i remember another coolant) just want to har confirmation from someone before i stick it on.

1st picture That nipple connects to the check valve from the oil filler.



2nd picture the yellow cirled nipple on the MANIFOLD goes to the Brake booster. The one oine the THROTTLE BODY goes a water line for the cold start.



3rd Picture I have no Idea what the hell that is..........Never seen anything like that before....LOL





I know its a little late to say this now but you should have labled them before you took it out!!! Other than that honestly I have never seen a throttle body like that before. I would just remove everything that is not needed.



I know this isn't a whole lot of help but without having seen the way it was installed it makes it difficult

ok, i finished up the TB mod. This is with the 1st set of butterflies taked out. And everything associated with them. As for the coolant line going through there and stuff, im just gonna block it off with jb weld. You can see i took off the stuff. Should work fine.
