I don't know where the vacume line going into the fire wall, hooks up to, under the dash, on my 92 2.5 . Right now, it has a home, wrapped around my master cylinder, but, would really like to know where it actualy belongs:
really I do not know the real purpose of it, I do know it has something to do with the heater defroster, if you ever pull your dash you will see the actuator up high in the middle behind the dash, you have two vac lines going to your heater control, and one of those lines goes to that actuator. Like I said, I do not know the real purpose of them, but that is where they go, mabye someone else will chime in and let us both know.
