Keep your rear ABS wheel speed signal flowing cleanly with the Standard Ignition ABS Wheel Speed Sensor Wiring Harness (ALH139). It drops in as a direct-fit replacement for the 2015-2018 Toyota Tacoma, restoring the wiring path between the rear wheel speed sensor and the vehicle's ABS circuit.
This harness carries the low-voltage signal from the rear wheel speed sensor toward the ABS system, providing the connectors and routing needed for that circuit to communicate.
Signs the harness may need replacing include an illuminated ABS warning light, an intermittent or lost wheel speed reading, or visibly chafed, corroded, or damaged wiring at the rear. Because those symptoms can have other causes, diagnose the circuit first; if a faulty harness is the cause, this replaces it.
