Hey all! A friend and I are rebuilding a project 1986 sr5 hatchback, and I was looking for some help on how to wire these since I cant find them in the manual, along with another part that was in the backseat when we towed the car. Thanks and good luck with your builds (pics linked below)

That's the tvis valve. It is mounted underneath the intake manifold. There should be a diaphram, vacuum canister, and a vsv. Just Google tvis vacuum schematic, MR2 should have the same vacuum wiring.

I'm pretty sure those solenoids and vacuums and diaphragms are for the a/c idle up and the IACV.

Might also be a charcoal canister. Can't really tell, plus I just woke up LOL.

Study this:
