1965-67 Chevelle Console Neutral Safety Switch (Powerglide)
The 1965-67 Chevelle Console Neutral Safety Switch (Powerglide) 1965–1967 Chevrolet Chevelle and El Camino Neutral Safety Switch (for automatic models equipped with a 2-speed Powerglide transmission and a factory center console) is a critical reproduction electrical component. It performs a dual safety and functional role: preventing the engine from cranking while the vehicle is in gear, and simultaneously acting as the activator for your rear backup/reverse lights. [1, 2]
Product Features & Specifications
- OEM Reference Number Interchange: Directly replaces obsolete GM Part # 1993696 (GM Group #: 4.054). [1, 2]
- Dual-Function Circuitry: Features built-in contact points for both the starter solenoid safety loop (preventing accidental lunges) and the reverse lamp circuit. [1]
- Mounting Location: Engineered exclusively to mount right onto the side of the factory floor-mounted console shifter assembly inside the cabin (not intended for column-shift configurations). [1]
- Wiring Scheme: Typically features factory-matched wire leads or terminal configurations to link seamlessly with your original dashboard harness extensions. [1]
- Average Cost: Sold individually (each) for roughly $54.99 to $72.99 depending on the brand and retailer.
Installation & Adjustment Notes
- Accessing the Switch: To replace this unit, you must disconnect your battery, remove the chrome shifter T-handle, and unscrew the center console top plate cover to expose the inner floor shifter mechanics.
- Harness Identification: When routing your connections, look for the heavy-gauge purple and purple/white wires (which dictate the starter loop) alongside the light green and pink wires (which power the backup lights).
- Critical Fine-Tuning: The switch housing features curved, elongated mounting slots. If your car won’t crank in “Park” but starts fine in “Neutral” (or if your backup lights stay on when in Drive), loosen the two 7/16-inch retaining nuts slightly. Slide the switch body incrementally forward or backward along its bracket until the internal contacts perfectly align with your shifter detent gates before tightening it down.
