Standard Ignition US-103 Ignition Switch

Ignition Switch for Tilt-Column Chrysler and Dodge Applications

Standard Ignition US-103 is an ignition switch built for select Chrysler, Dodge, and Plymouth vehicles with tilt steering columns. It uses a bolt-on mounting design, a rectangular female connector, and 11 male blade terminals for a direct service replacement on listed applications.

Key Features

• Fits select 1977-1989 Chrysler, Dodge, and Plymouth vehicles with tilt steering wheel or tilt steering column applications
• Bolt-on attachment method for secure column mounting
• Rectangular 1-connector design with female connector gender
• 11 male blade terminals for the specified vehicle electrical layout
• Black and silver housing with aluminum and plastic finish
• Copper alloy conductors for strong electrical conductivity and reduced resistance
• 100% tested for mechanical and electrical switching performance

Detailed Description

Standard Ignition US-103 is an ignition switch engineered for service replacement on older Chrysler, Dodge, and Plymouth platforms that use a tilt steering wheel setup. The switch is built with high-grade materials and copper alloy conductors to support consistent electrical transfer and proper switching action. Standard Ignition US-103 is a practical choice when restoring starting and accessory circuit function on vehicles such as the Dodge D100, Dodge Ramcharger, and Chrysler Fifth Avenue.

This part cross-references Standard Ignition US-103 with OE-style replacement numbers such as 1S6126 and CS104 for the same application.

What It Helps Fix

• Intermittent no-start conditions caused by worn ignition switch contacts
• Accessory power loss when the key is moved through switch positions
• Electrical switching issues in the steering column ignition circuit
• Starting problems related to damaged or fatigued internal switch components
• Fitment issues on tilt-column vehicles needing the correct terminal layout

Installation Notes and Tips

Verify the vehicle has the listed tilt steering wheel or tilt steering column configuration before ordering. Match the connector shape, terminal count, and mounting style to the original switch, and compare the existing column hardware and wiring layout to the US-103 before installation. This ignition switch is listed for column mounting and should be installed only on the applications shown in the fitment data.

Quality Assurance

Standard Ignition states that this switch is built from robust materials and tested for both mechanical and electrical switching performance. The design uses copper alloy conductors to support reliable conductivity and low resistive loss.
