See Figures 1 through 192
Each vehicle is equipped with a decal containing emission control data specific to that vehicle and engine. The decal is typically located on the underside of the hood, but might instead be found on the fan shroud, the coil appearance cover or elsewhere. These specifications are critical to the effective servicing of the applicable system. In addition to the tune-up specifications and procedures, the emission control data decal includes a color-coded schematic of the engine vacuum system. The color coding on the schematic represents the actual color coding on the vacuum hoses, although there may be some exceptions.
Since this information covers approximately two hundred calibrations, all of which correspond to a specific vacuum diagram, it is not feasible to include a schematic of every vacuum system. In addition, mid-year production changes often result in different vacuum schematics from those which are published. For this reason, the best source for vacuum diagrams is the vehicle's emission control data decal. The following vacuum diagrams cover most, but not all, calibrations pertaining to the 1979-88 Mustang and Capri. For ease of use, these diagrams are arranged by engine size within each model year.
If your exact calibration is not covered here, use a similar configuration as a guide or see your local dealer about purchasing a replacement sticker.
