Detailed Description

This ABS wheel speed sensor wiring harness is engineered for front-wheel service on Buick Regal, Buick LaCrosse, and Buick Allure applications listed above. Standard Ignition ALH297 is built with OE-style connectors, sealed terminals, and routing aids that support a clean repair where the original harness has been damaged, corroded, or compromised by heat and road exposure. The harness construction uses glass-reinforced plastic resin and a protective sleeve to help maintain durability in demanding underbody conditions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• ABS warning light caused by a damaged front wheel speed sensor harness
• Intermittent wheel speed signal loss from broken or corroded wiring
• Short circuits caused by chafed insulation or exposed conductors
• Water intrusion at the connector interface
• Poor harness routing after prior repair or collision damage

Installation Notes and Tips

Verify the connector shape, terminal style, and front-position routing before installation. Inspect the mating connector, clips, and grommets on the vehicle harness for wear or contamination, and replace any damaged retaining points so the harness sits correctly in the chassis path. Confirm the repair against the vehicle’s ABS wiring layout for the listed Buick Regal, Buick LaCrosse, or Buick Allure application.

Quality Assurance

Standard Ignition supplies this harness with OE-quality connector and terminal construction to support dependable electrical contact and a secure fit in the original routing path.
