    EGR Vacuum Regulator?

    My EFI harness calls out a EGR Vacuum regulator. 



    Where does this go?  What does this do? I can't find a vacuum diagram for foxbody era mustang.

    Here's a link to many things efi, and vacuum, for mustangs of the fox era.  Scroll down to the vac diagram.  The regulator is in the upper left corner of the drawing.

    Re: EGR Vacuum Regulator?

    It sends vacuum to the egr valve using  a signal from the pcm. There is usually a red plastic line from the regulator to the egr valve on the stock FORD vacuum harness.
