Ignition Switch for Tilt-Column Applications

Standard Ignition US-131 is an ignition switch built for service replacement on a wide range of GM and Pontiac vehicles. It uses a bolt-on mounting style, a rectangular female connector, and a 9-blade male terminal layout for direct electrical interface in column-mounted applications.

With copper alloy conductors and 100% electrical and mechanical testing, this ignition switch is built to maintain consistent switching performance in vehicles such as the Chevrolet S10, Pontiac Firebird, and Buick Skylark.

Key Features

  • Bolt-on attachment method for column mounting
  • Female rectangular connector with 1 connector interface
  • 9 male blade terminals for electrical connection
  • Copper alloy conductors for low-resistance current flow
  • 100% tested for mechanical and electrical switching performance
  • Built with high-grade materials for service replacement use

Detailed Description

Standard Ignition US-131 is an ignition switch replacement for vehicles that use a column-mounted switch design. The part number US-131 is engineered to match the electrical and mechanical requirements of the original switch, helping restore reliable key-to-start and accessory switching operation. This ignition switch is listed for many 1984-1994 GM-platform vehicles, including Chevrolet Camaro, Pontiac Grand Am, and Oldsmobile Cutlass Ciera applications with the specified steering column and console-shift configurations where noted.

This part cross-references Standard Motor Products US-131 and AC Delco-style applications for the same use case.

What It Helps Fix

  • Intermittent no-start conditions caused by worn switch contacts
  • Loss of accessory, ignition, or start circuit function
  • Electrical switching problems from heat- or age-related wear
  • Key position issues in column-mounted ignition systems
  • Unreliable operation in tilt-steering-wheel applications

Installation Notes and Fitment

  • Fits 1984-1986 Chevrolet Camaro, compatible with vehicles with tilt steering wheel.
  • Fits 1984-1986 Chevrolet S10, fits vehicles with tilt steering wheel and console shift.
  • Fits 1984-1988 Pontiac Fiero, fits vehicles with tilt steering wheel and console shift.
  • Fits 1987-1990 Buick Skylark, fits vehicles with tilt steering wheel and console shift.
  • Fits 1990-1992 Chevrolet Camaro, N/A.
  • Fits 1991-1992 Pontiac Firebird, N/A.
  • Fits 1984-1990 Pontiac Bonneville, fits vehicles with tilt steering wheel and console shift.
