Hazard Warning Switch Connector for 1985-1991 Ford F-150 & More - Standard Ignition S-622

Replace a burned, corroded or broken plug at the switch with this Standard Ignition switch connector, part number S-622. It is listed as both a Hazard Warning Switch Connector and a Headlight Dimmer Switch Connector. It is a replacement for many Ford, Lincoln and Mercury vehicles, including the 1985-1991 Ford F-150 and 1979-1989 Ford Mustang.

The connector joins the vehicle's wiring harness to the switch and carries the circuit the switch opens and closes. Signs that the connector may need replacing include melted or corroded terminals and headlight beam selection or hazard flashers that cut in and out. If a failed connector is the cause, this part replaces it. Diagnose the circuit first, because the switch or the wiring can cause the same symptoms.
