Detailed Description

Standard Ignition ALH156 is a rear ABS sensor harness for vehicles that use a dedicated wheel speed sensor wiring connection at the chassis. It is built with two female connectors and two female eye ring terminals, and the oval connector design supports a direct-style replacement for the original harness layout. This part cross-references ARA4139 for the same application. Standard Ignition ALH156 is a practical choice for restoring the wiring path on a Cadillac XLR or Chevrolet Corvette when the original harness is damaged, brittle, or no longer maintaining a stable connection.

The harness construction includes a protective sleeve to reduce abrasion, while the included grommets and wire clips help maintain factory-style routing. The glass-reinforced plastic resin adds durability in high-temperature and harsh underbody conditions.

Common Problems This Part Can Help Solve

• ABS warning light caused by damaged rear wheel speed sensor wiring
• Intermittent sensor signal from corroded or loose harness connections
• Short circuits from chafed or exposed wiring
• Water intrusion at the connector interface
• Poor harness routing after prior repair or underbody damage

Installation Notes and Tips

Verify rear-position routing before installation and compare the connector shape, terminal style, and mounting points to the original harness. Inspect nearby clips, grommets, and the sensor lead path for wear before securing the replacement. Confirm all electrical connections are fully seated and protected from abrasion after installation.

Quality Assurance

Standard Ignition focuses on OE-style replacement electrical components, and this harness is built with water-tight connector interfaces, durable resin construction, and protective routing features to support dependable service in demanding chassis locations.
