Here is an exploded version on ToyoDIY.com, and the part number.  The A/C cooling unit is under the dash on the passenger side.  Here is a the FSM steps for Removing the Cooling Unit or  The complete '93 FSM.

You should check pink wire going to the cooling temp sensor. On the back of the in-take manifold there a cooling temp a/c cut off switch witch needs to see a ground signal to work.  This is a common problem with the 3.0l 4runner. You should check this before going into the dash, its easier.  Good luck.
