Some 1985-88 vehicles may have an electrical connector at the vehicle speed sensor (VSS), which is improperly labeled. The connector will work
properly but could cause confusion if electrical troubleshooting is necessary. Figure No. 1 shows a properly labeled connector. The improperly labeled
connectors have the "A" and "C" reversed. All Service Manual terminal call-outs use the labeling as shown in Figure No. 1.
