Replace a melted, corroded or brittle relay plug with the Standard Ignition S-659 Accessory Relay Connector. It is the plug-in pigtail a relay seats into, used on circuits such as the fuel pump relay, the ABS relay and the horn relay. It is a direct-fit replacement for many vehicles, including the 1980-1995 Ford F-150 and 1981-1996 Ford Mustang. See the "Vehicles it fits" section for the full list.
This is the connector and wiring pigtail only; the relay itself is not included. It is cataloged for the auxiliary position and is listed under both Relay and Accessory Relay Connector.
- Built to OE standards: Manufactured to exact OE standards in TS16949- and ISO9001-certified facilities and designed for specific vehicle applications.
- Checked throughout production: Each connector goes through quality checks and testing at every stage of manufacturing.
- Factory-assembled pigtail: Arrives assembled with a 7 in (177.8 mm) wiring harness of five 14-gauge wires. It is designed so installation does not require specialized tools. Splice connectors are not included.
- Connector specs: Square plastic connector with five female blade terminals, metal contacts and push-on attachment. A dust shield is not included.
A relay connector links the vehicle wiring harness to the relay's terminals. If a damaged connector is the cause of an intermittent circuit, this part replaces it. Diagnose the circuit first, because a failing relay or damaged wiring can cause similar symptoms. Country of origin: Taiwan.

Frequently Asked Questions
Is this a relay or a relay connector?
It is the accessory relay connector: a square plastic plug with a 7 in wiring pigtail that the relay plugs into. The relay itself is not included.
Is this the connector for a 1981-1996 Ford Mustang relay?
The S-659 is listed for the 1981-1996 Ford Mustang among its applications. Check the "Vehicles it fits" section to confirm it matches your vehicle.
What wire gauge and how many wires does it have?
It has five 14-gauge wires in a 7 in (177.8 mm) harness, ending in five female blade terminals with metal contacts.
Are splice connectors included?
No, splice connectors are not included. Join the pigtail leads to the harness using the method in your vehicle's service information.
What are signs a relay connector may need replacing?
Signs include melted or discolored plastic, corroded or loose terminals, and a circuit that works intermittently. Diagnose first, since a bad relay or damaged wiring can cause the same symptoms.
