Suzuki Samurai VSS Wiring Diagram - Vehicle Speed Sensor to ECM Pin A7

This document is a simple wiring diagram for the Vehicle Speed Sensor (VSS) circuit, uploaded to the gallery of a 1986 Suzuki Samurai. The diagram shows the ECM (item 1) connecting through the ECM coupler (item 2) at terminal A7. A yellow (Y) wire runs from ECM terminal A7 to a coupler (item 5) at the speedometer (item 4), which houses the VSS (item 3). A black (B) wire from the coupler goes to chassis ground. A legend identifies the five numbered components: ECM, ECM coupler, VSS, speedometer, and coupler. Below the schematic is a connector face view of the ECM couplers, with the location of terminal A7 marked on the right-hand connector block, allowing a technician to locate the correct pin when testing the VSS signal circuit. From this document, a reader can learn the wire colors used in the VSS circuit (Y for signal, B for ground), the ECM pin (A7) that receives the vehicle speed signal, and that the VSS is integrated into the speedometer assembly. The document itself carries no year, model, or part-number information; it is one page of a larger set of circuit diagrams uploaded to the same album.
