Detailed Product Overview

Built for the rear left position, this Standard Ignition ALH134 harness is made for Toyota Tacoma ABS service where the original sensor lead has damaged insulation, broken terminals, or an unreliable connection. The harness uses a female connector layout and blade terminals to match the vehicle-side electrical interface, supporting consistent communication between the wheel speed sensor and the ABS control system. Standard Ignition ALH134 also cross-references 1P3783 for the same application.

Common Problems This Part Addresses

• Loss of rear wheel speed signal at the ABS module
• Corroded, cracked, or damaged sensor wiring near the wheel area
• Connector fitment issues at the rear left sensor harness
• Brake system fault codes related to wheel speed sensor wiring

Installation Notes and Tips

Verify the rear left position and connector style before installation. Inspect the sensor, terminals, and nearby wiring for corrosion or physical damage, and route the harness away from moving suspension components and heat sources. Confirm all electrical connections are fully seated after installation on the Tacoma.
