That looks like the "idle up" VSV and the regulator thingy the air bleed adjustment for the air conditioning idle up function..

Don't have that specific vehicle or info on it, but the VSV shown and the "regulator" is identical to the AC idle up hardware used on an '88 Camry 4 banger.. The VSV is wired in parallel into the AC electrical controls so that it does it's thing when the AC compressor clutch is engaged..
