Riyhch Park/Neutral & Backup Lamp Safety Switch 352-3201 — Direct-Fit for 1995–2003 GM, Includes Harness

The Riyhch Park Neutral Position and Back-up Lamp Safety Switch #352-3201 is a direct-fit replacement switch and harness assembly that restores proper neutral/park detection and reverse lamp operation for compatible 1995–2003 GM vehicles.

If your vehicle shows erratic starting behavior, the transmission won’t engage in Park or Neutral, or the reverse lights fail to illuminate, a worn or failed neutral/backup safety switch is a common cause. This Riyhch assembly is listed to match OE numbers (352-3201, 24298931, 24229422 and others) and comes with the connector wire harness to simplify installation. It replaces the factory safety switch used across a wide range of Chevrolet, GMC, Cadillac, Hummer and related models from the late 1990s to early 2000s.

How will this switch affect my vehicle’s starting and safety systems?

When functioning correctly, the neutral/park safety switch prevents the engine from starting in gear and enables reverse lights when the transmission is in reverse. Replacing a faulty switch restores those interlocks and lighting signals so the vehicle is safer and compliant with road expectations. The harness-ready assembly reduces wiring troubleshooting during installation.

• Resolves no-start conditions related to park/neutral detection
• Restores reverse lamp activation for visibility and signaling
• Includes connector harness for plug-and-play or near plug-in fit
