The 1998-2000 Rangers are not equipped with a VSS (Vehicle Speed Sensor). The PCM (Powertrain Control Module) receives vehicle speed information from the antilock brake system rear wheel speed sensor. The raw signal from the ABS/VSS sensor on the rear axle goes directly to the 4WABS module where the signal is corrected for tire diameter. Then the corrected signal is sent out on the gray/black to the PCM, speed control, cluster, etc. In this system, the PCM is an end user of the corrected VSS signal. How to connect yours to it ?? So you must have at least a 98 trans.
