Everywhere you look online will will find conflcting information regarding which coil connector is compatible with your vehicle. Even Ford doesn't have the compatibility information complete and consistent. The best and easiest way to determine which coil connector you need is to remove your connector and check the color of the terminal wedge in the front. If it's red...this is the replacement. If it's yellow then you need the other one that looks identical: CLICK HERE WPT-579 They are not interchageable as the wire teminals themselves are different sizes. I have both connectors available and they are the same price. They are GENUINE. Includes ALL NEW PARTS: Connector housing: (30% glass reinforced. Chinese version: not so much) 8 of them. Connector seal: quantity = 8 Terminal wedge: quantity = 8 Wire terminals: quantity = 16 Wire seals: quantity = 16 *You will want to reuse your origial factory wiring to maintain consistency with wire identification. Avoid using the generic white or black wires provided with aftermarket cheap replacement connectors, they are not 100% copper. They are at best copper clad aluminum. ELECTRICAL SPECIFICATIONS (Cheap Chinese connectors actually allow arcing): Voltage: 250V Current: 22.0A Contact Resistance: 10 milliohms max. Dielectric Withstanding Voltage: 500V DC Insulation Resistance: 20 Megohms min. INSTRUCTIONS: NO SPECIAL TOOLS NEEDED: Since you are replacing your broken connectors, feel free to break them apart....you have new ones. Do be careful not to damage, crush or otherwise deform the wire terminals. 1. From the front of the connector pull out the terminal wedge (the red part). It will likely break. 2. From the front of the connector, insert your chosen tool (toothpick, straight pen or similar devise) to push the terminal retainer down. Gently pull on the wire from the back side. 3. Insert the wire assemblies you just removed into your new connector housing.taking note of their orientation and position. You should hear each click into place. 4. From the front of the connector housing, push the red terminal position assurance device in. 5. Install connector assembly on the ignition coil.
