I assume you have AC controls and wiring. If not, you'll have to source the the controls. The wiring should be there.
Largely, you've got two options:
1) Use your 22RE compressor and the 2RZ/3RZ AC mount. You need to convert the clutch of the compressor to a 4-rib pulley, which is standard on 1st gen MR2s (I found indications that it may be common on 4-cylinder mustangs late 80s).
2) Use the 2rz/3rz compressor and build custom AC lines.... As you don't have AC lines, this may be a better option...
The rest of it you'll have to add from another 4runner - standard AC parts like evaporator, condenser, dryer, etc. Use appropriate seals for R-134a and buy a new expansion valve if you really want to do the conversion right.
You need to have the factory tach powered to trigger RPM on the AC amplifier.
No my truck is a DLX and never has had AC. That is a
