Vacuum Routing '94 5.0L
For the label specific to YOUR vehicle, click
this link, then click "Quick Guides" in the sidebar, then click "VECI Labels" and find the calibration code on the sticker on your EEC. On '87-91 F-series & Broncos, it's in the driver's kick panel. '92-96 is in the same place, but it's not easily visible without removing the EEC into the engine compartment. With some effort, it can be seen by removing the driver's kick panel & looking between the cowl & e-brake, or by removing the e-brake pedal assembly. Some '92-96 trucks also have the calibration code on a sticker in the door jamb, but it's hit-or-miss; I haven't found any pattern.
For carburetors, try this:
