Just a few more hoses to go b4 liftoff.
I have all the vacuum lines hooked up except for a few. On the back of the throttle body, there is a green plastic part that has two tubes sticking out, what hoses are suppose to go to this peice? Then there is a hose on the back side of the throttle body, that is one big hose going to a contraption with 4 or six little hoses coming out, where do these go, because I don't have this on the car. Then there is one more under the throttle linkage coming out of that vacuum thing, where is that hose suppose to go, I can't find it anywhere, even in the manual. It is an 87 TII motor in an 86 gxl, and it was converted to manual. Thanks for everyones heip, it has helped a lot with me hooking up all these other vacuum lines today.

I already Have this. Look at the upper corner, see the part labeled (D) what hoses go to this? And the hose that goes to a plastic peice with 4 or 6 hoses coming off of that, what is that for, because I do not see that in the engine bay. (It is all the wat to the right on the picture.)

You should have four metal nipples on the back of the throttle body. The bottom nipple is the only one that has a vacuum coming FROM the throttle body. That one goes to either nipple on the plastic thermowax . The other nippple on the plastic thermowax goes to a diaphram on the fwd, left side of the throttle boby.
Now you have three other metal nipples to deal with. The large nipple goes to the black plastic spider that has four other plastic nipples on it. Those four go to the oil injector nipples.
Now you have two metal nipples left. One goes to a place b/t the two oil injectors on the intake manifold. You can see it in the diagram. It sticks straight up b/t the injectors.
Now you have one metal nipple left. Cap it off.
Remember, of the four metal nipples on the back of the throttle body, only one pulls a vacuum. The top three originate prior to the throttle plates and are a source of filtered air, so you don't want to confuse any of the top three with the bottom one.
EDIT; The plastic thermowax I refered to is in the diagram and is ITEM *D* in the left corner of the schematic. Has two plastic nipples.

Thanks, so on that thermowax thing, I just leave one of the nipples uncapped and the other nipple goes to the vacuum booster thing under the throttle linkage, got it.

There is a jpg attached below. The upper picture shows the valve and a hose running from your right to the left of the throttle body to a diaphram. That one hose. The other hose goes from the other plastic nipple on the thermo valve, to the row of four metal nipples on the back of the throttle body. It goes to the BOTTOM metal nipple. Of the three metal nipples left, the large nipple goes to the black plastic spider that has four of its own plastic nipples that go to each oil injector. One of the remaining metal nipples(pipes if you will) goes to the metal nipple that sticks straight up b/t the oil injectors on the intake manifold. The remaining metal nipple getss capped unless someone can come up with an alternative. Mines capped. Car works plenty good fine keemasabe as described.
