2017-2023 Tesla Model 3 Rear Bumper Wiring Harness | 1067959-00-E

The Quiet Controller of Your Model 3’s Rear End

What It Actually Does (Beyond “Wires”)

• Taillight Precision: Powers the full array of rear lights—brake lights, turn signals, reverse lamps, and even the subtle LED strip that runs across the trunk. No more dim spots or delayed braking signals that confuse drivers behind you.
• Parking Sensor Smarts: Connects the rear parking sensors to your Model 3’s display, turning beeps into clear visual alerts when you’re inches from a curb or another car. Ever had a sensor “glitch” and stay silent? Chances are the harness was failing.
• Backup Camera Clarity: Transmits crisp video from the rear camera to your touchscreen, even in rain or darkness. A frayed wire here can turn your backup view into a fuzzy mess—this harness keeps the signal strong.
• Collision Readiness: Works with the rear impact sensors to trigger hazard lights automatically if you’re hit, and ensures the trunk release (linked to the bumper) responds instantly when you tap the screen.

How to Tell It’s Time to Replace

• Rear Lights Play Hide-and-Seek: Brake lights that work sometimes, or a turn signal that flickers like a dying bulb (even with new bulbs). The harness is losing its grip on the connection.
• Sensor Silence: No beeps when reversing toward a wall, or “Rear Sensor Unavailable” popping up randomly. The wires carrying sensor data are likely damaged.
• Camera Fuzz or Freezes: The backup view pixelates, cuts out, or takes forever to load. This harness delivers the camera’s signal—if it’s weak, so is your view.
• Trunk Troubles: The trunk won’t pop open when you tap the screen, even though the battery’s fine. The harness connects the trunk release to the bumper’s electrical system—if it’s broken, so is the link.

Why It’s Built Better Than Aftermarket

• Wires That Outlast the Car: Made with thick, heat-resistant insulation that handles summer trunk heat and winter cold without cracking. Bend it, vibrate it, expose it to road grime—years later, it still performs.
• Connectors That Cling: Gold-plated ends that lock into place, so hitting a pothole won’t jostle the connection loose. No more “fixing” it by wiggling the wires.
• Weatherproof to the Core: Wrapped in a rubbery sheath that repels rain, snow, and road salt (critical if you live where they salt the roads). No rust, no corrosion, no short circuits.
• Fits Like It Grew There: Designed only for 2017-2023 Model 3s, with pre-cut lengths that tuck neatly behind the bumper. No extra wire to bundle, no missing clips—just plug and secure.

What You Get (And Why It’s Worth It)

• The 1067959-00-E harness, ready to install.
• A simple guide with photos showing where it routes behind the bumper (no guesswork).
• 2 years of warranty—if it fails because of a defect, we replace it.
