I recently completed a bunch of work on my 85 van (3 yec). I labelled all of my connections before removing the intake and was very careful. Apparently not careful enough, because I have a missing connection to the VSV with part #89570-28060. I'm missing the cap (I don't think a hose goes there) to the back side of the VSV. See image below. Will someone confirm that there is no hose connection here and if it is a cap, it is necessary to have this cap on the nipple?
