Standard Ignition ALS3949 uses a single-bolt mounting style at the spindle and a direct, snap-fit attachment method to match the original-style installation layout. The included harness and rectangular connector help support a straightforward electrical connection, while the 24.5-inch lead length provides routing reach for the application. If you are replacing a failed ABS wheel speed sensor on an INFINITI QX50 or INFINITI QX55, ALS3949 is built around the specified fitment and connector configuration.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRestoring wheel speed signal input to the ABS system\u003c\/li\u003e\n\u003cli\u003eAddressing ABS warning lights caused by sensor failure\u003c\/li\u003e\n\u003cli\u003eReplacing damaged connector or harness sections at the spindle\u003c\/li\u003e\n\u003cli\u003eCorrecting intermittent wheel speed data from a worn sensor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify connector style, terminal count, and mounting location before installation.
