Front Electronic Module (FEM) Harness Assembly for Tesla Model 3 (2020) | 1567961-00-A

Why This Harness Assembly Matters

What It Controls (And Why That Matters)

• Lighting Precision: Powers and synchronizes LED headlights, daytime running lights, and turn signals, ensuring they activate instantly (no lag) and dim/brighten smoothly with Tesla’s auto-adjust feature.
• Sensor Synergy: Connects front parking sensors, rain-sensing wipers, and forward-facing cameras to the FEM, so your Model 3 can detect obstacles, adjust wiper speed, and enable Autopilot’s lane-keeping (when activated).
• Weather Resistance: Safeguards connections between the FEM and exterior components, preventing water or debris from disrupting signals—critical for reliable performance in rain, snow, or dusty conditions.

Signs Your FEM Harness Needs Replacement

• Intermittent Front Lights: Headlights flickering, turn signals not activating, or DRLs cutting out randomly. These are classic signs of frayed wires or loose connectors in the harness.
• Sensor Malfunctions: “Parking Sensor Unavailable” alerts, wipers not responding to rain, or Autopilot features disabling unexpectedly. The harness may be failing to transmit data from front sensors to the FEM.
• Burning Smell or Fuses Blowing: A melted wire inside the harness can cause electrical shorts, triggering blown fuses or a faint burning odor near the front bumper—immediate replacement needed to prevent fire risk.

Built to Tesla’s Exacting Standards

• OEM-Grade Materials: High-temperature, automotive-grade wiring (rated to 125°C) with abrasion-resistant insulation, designed to withstand engine bay heat and vibration without cracking.
• Precision Connectors: Gold-plated terminals that ensure zero signal loss, even after years of thermal expansion and contraction. No “loose connection” gremlins.
• Weather-Sealed Design: All junction points are sealed with silicone gaskets, keeping moisture, dirt, and road salt out—critical for longevity in harsh climates.
• Plug-and-Play Fit: Engineered exclusively for 2020 Model 3, with pre-crimped wires and color-coded connectors that match your vehicle’s factory layout. No cutting, splicing, or guesswork.

Installation & What’s Included

• 1x FEM Harness Assembly (1567961-00-A) with all integrated wires and connectors.
• Digital Installation Guide: Detailed diagrams showing routing paths (to avoid pinch points) and torque specs for mounting clips (8 Nm).
• Note: Professional installation recommended—requires access to Tesla’s diagnostic system to reset the FEM after replacement, ensuring all sensors sync correctly.

Warranty & Peace of Mind

• 2-Year Limited Warranty: Covers defects in materials (e.g., faulty insulation, connector failure) and workmanship. We guarantee it will perform like the original.
