Were is speed sensor on 1999 Ford Ranger manual transmission?

The 1999 Ford Ranger with a manual transmission doesn't have a Vehicle Speed Sensor (VSS) in the same location or with the same function as an automatic transmission. Manual transmissions use the output shaft speed to determine vehicle speed, indirectly, through other sensors. There's no single sensor dedicated solely to this.

The information needed for the speedometer in a manual Ranger comes from:

* The Speedometer Cable: This is the most direct method. A mechanical cable runs from the transmission to the speedometer in the instrument cluster. The cable's rotation directly drives the speedometer needle.

Therefore, there's no "speed sensor" to replace in the traditional sense. If your speedometer isn't working, the problem is much more likely to be within the cable itself (broken, disconnected, seized), the speedometer gear in the transmission, or a problem with the speedometer gauge in the instrument cluster.
