Oh man, I had the same problem at the end of my rebuild. Search around on here, there was someone who posted a picture of that side of the plenum and had everything numbered. Made it suuuuper easy. If I can find the post I'll link it but I would just start searching now if I were you.

Here's the good stuff from that thread(even though it's for a 95, so it may not be exactly the same).
and this
Here's some others for a 91 3VZE from someplace else.
KHIG:
Here are all the hoses on the pass side of the plenum. The item numbers correspond to your picture with the numbers. Toyota numbered the vacuum hoses and it looks like yours are still numbered correctly from your pictures. The vacuum hoses are the small hoses and the larger hoses are air hoses, fuel hoses, brake booster, and PCV hoses. I list the Toyota vacuum hose numbers as printed on the the hose itself as well as where it goes. Front and rear refer to the truck front or rear. There are three VSV's (rear, center, and front) and one AC idle up valve.
1. Reed valve
2. Fuel return hose
3. Brake booster
4. Rear air hose at the AC idle up
5. PS pump valve
6. Front air hose at the AC idle up
7. Vac hose #1 to pass side of rear VSV
8. Vac hose #2 to pass side of center VSV
9. PCV hose
10. Vac hose #5 to driver side of center VSV
11. Vac hose #3 to pass side of front VSV
12. Vac hose #6 to driver side of front VSV
13. PS pump valve
Vac hose #4 goes from driver side of rear VSV to the reed valve
AC idle up vacuum hoses:
- pass side to diaphragm (very short hose)
- driver side tee's into vacuum hose #2 (item 8 in your picture)
Hope this helps,
Bugs
