Detailed Description

Standard Ignition US-170 is an ignition switch for 1989-1992 Ford Probe models that mount on the steering column. The switch is engineered with a robust housing and precision electrical contacts to restore proper ignition circuit operation, including key-position switching for start and run functions. If you are searching for a Ford Probe ignition switch replacement or a Standard Ignition US-170 cross reference for the same application, this part is built to match the listed connector and terminal layout.

This part cross-references 1S6208 and CS306 for the same application. Standard Ignition US-170 is also a relevant search term for buyers looking for a 1989 Ford Probe ignition switch, 1990 Ford Probe ignition switch, 1991 Ford Probe ignition switch, or 1992 Ford Probe ignition switch.

Common Problems This Part Can Address

• Intermittent no-start condition caused by worn ignition switch contacts
• Key position failure between accessory, run, and start circuits
• Electrical switching issues from heat- or age-related terminal wear
• Loose or inconsistent column-mounted switch operation
• Voltage loss through degraded internal conductors

Installation Notes and Tips

Verify the connector count, terminal style, and column mounting style before installation. Compare the existing switch to the US-170 to confirm the rectangular connector shape, 4-connector layout, and 9 blade terminals match the vehicle’s original configuration. Because this is a bolt-on ignition switch, proper alignment on the steering column is important for correct key-position operation.

Quality Assurance

Standard Ignition states that this switch is made with high-grade materials and copper alloy conductors, then fully tested for both mechanical and electrical switching performance. That testing helps confirm proper operation before the part is put into service.
