Early E4OD's had a mechanical provision for a speedometer drive. The Bricknose 87-91 E4OD Equipped trucks had a cable driven speedometer, with a provision for a VSS inline for cruise (if equipped) and to feed vehicle speed to the TECA (Transmission Computer). In 92 when the release of the OBS, the speedometer is electronic (as is all them through current) and the speedometer feed is from the VSS in the top of the read differential. The VSS is fed to the PSOM (the electronics that feed the digital odometer and the speedometer) and the TECA for the Transmission.

The late E4OD's and the 4R100's behind the 7.3PSD's also use the VSS in the rear diff for speed, but it is fed to the PCM and it controls the transmission and the instrument cluster.
