Mechanical to Electrical Speedometer Adapter
The Trail Gear Mechanical to Electrical Speedometer Adapter is the essential component for Toyota owners performing gear-driven transfer case swaps. If you are installing a gear-driven case into a later-model Tacoma or 4Runner, this adapter bridges the gap between your new mechanical output and your vehicle's factory electronic speedometer.
The Solution: Seamless Signal Conversion
Modern Toyota speedometers rely on an electrical signal, while older heavy-duty transfer cases utilize a mechanical cable drive. This adapter simply screws onto the mechanical speedometer sensor output and converts rotation into a high-quality electrical signal. By plugging directly into your existing vehicle speed sensor (VSS) wiring harness, it eliminates the need for complex custom dash modifications.
Key Benefits
- Plug-and-Play Integration: Designed to screw onto your mechanical sensor and snap into your factory 3-pin Toyota wiring harness.
- Precision Signal: Provides an accurate electrical reading to your speedometer, ensuring your dash remains functional after a transfer case swap.
- Versatile Application: While perfect for Toyota Tacoma and 4Runner swaps, it also serves as a high-quality replacement for various import vehicle speed sensors.
Technical Specifications
- Thread Pitch: Compatible with all Toyota mechanical speed sensors featuring a male M22-1.50 thread.
- Connector Type: Accepts standard Toyota 3-pin speedometer sensor plugs.
- Direct Replacement: Replaces OEM Part Numbers: 89711-88100,97010,8937-79200, SU5426, 5S4595, and VSS21.
