i have an 89 4 runner 22re and possibly california emissions.it was purchased in a box.i am ready for a test fire but seem to be missing a VSV (vacuum switching vave) i have 3 already mounted on the valve cover mounting plate.all vacuum lines are accounted for except 2 extra and a gray 2 wire connector.I already have the reddish brown,blue, and light gray VSV. the one that i think i am missing would be the closest to the front of the engine. If anyone knows the serial # for the missing one I would be grateful for the imformation.
