The **F2VF-4B-R** is a specific automotive-grade electrical connector component, typically part of a wiring harness system. This part number is associated with Ford Motor Company's component standards, but it is manufactured by various suppliers (like Aptiv or TE Connectivity) to meet those specific OEM requirements. --- ## 1. Technical Identification The part follows the standard Ford component naming convention. Here is a breakdown of the electronic and physical characteristics: | Feature | Specification | | :--- | :--- | | **Component Type** | Connector Housing / Receptacle | | **Number of Positions** | 4-Way (4 Pins) | | **Orientation** | Right-Angle or Specific Inline (Varies by harness) | | **Material** | High-temperature glass-filled PBT or Nylon | | **Color** | Black (Standard) | | **Mounting Type** | Wire-to-Wire or Wire-to-Device | --- ## 2. Key Electronic Features ### A. Terminal Compatibility The "4B" designation typically indicates the specific keying and terminal series used inside the housing. It is designed to hold **crimped terminals** (usually silver or tin-plated) that provide the actual electrical path. ### B. Sealing and Environmental Protection The "-R" suffix often denotes a **sealed** version or a specific revision involving a silicone rubber seal. * **IP Rating:** Designed to meet IP67 or IP69K standards when mated. * **Resistance:** Resistant to engine fluids (oil, gas, coolant) and high-pressure washes. ### C. Locking Mechanism * **Primary Lock:** An integrated plastic tab that clicks when the connector is fully seated. * **TPA (Terminal Position Assurance):** Often includes a secondary lock (usually a different color like red or purple) to ensure terminals do not back out under vibration. --- ## 3. Common Applications Due to its 4-pin configuration and ruggedized build, the F2VF-4B-R is commonly found in the following automotive electronic subsystems: 1. **Oxygen Sensors (O2):** Providing heater and signal paths. 2. **Ignition Coils:** Distributing power and trigger signals to spark plugs. 3. **Mass Air Flow (MAF) Sensors:** Connecting power, ground, and data lines. 4. **Lighting Modules:** Specifically for fog lights or auxiliary LED arrays. --- ## 4. Cross-Reference & Replacement If you are searching for this part for repair, note the following: * **Service Pigtail:** If the connector is melted, look for Ford Motorcraft service pigtail kits (often starting with the prefix `WPT-`). * **Terminal Removal:** Requires a standard terminal release tool (depressing the plastic tang inside the cavity).
