Installation Notes and Tips

Verify connector shape, terminal count, and switch functions before installation. This CBS-1173 uses a bolt-on attachment method and female rectangular connectors, so the replacement should match the vehicle’s original electrical layout. Confirm the Ford Excursion model year and inspect the harness terminals for corrosion or heat damage before connecting the new switch.

Quality Assurance

Standard Ignition builds this switch with durable materials and copper alloy conductors, then tests each unit for both electrical operation and mechanical switching performance. That validation helps support consistent function in lighting, turn signal, and wiper control circuits.
