VSS Speed Sensor, Ford EFI or Digital Speedo, Dana 20, 66-77 Ford Bronco SKU: 8285

Vehicle Speed Sensor (VSS) for Digital Speedometer | 66–77 Bronco Dana 20

Upgrade your early Bronco’s drivetrain for modern functionality with this Vehicle Speed Sensor (VSS), designed to replace the mechanical speedometer cable on 1966–77 Ford Broncos equipped with the Dana 20 transfer case. This VSS plugs directly into the stock transfer case and sends a digital speed signal to your digital speedometer and/or Ford EFI system. Ideal for Broncos running a factory Ford Speed Density or Mass Air Flow EFI swap or any other EFI setup requiring a VSS signal.

Not compatible with stock mechanical speedometers—digital or GPS speedometers are required. - If you need a VSS sensor and want to run the stock mechanical gauge, check out our VSS Speedometer Cable for Stock Gauge instead.

• Digital Speed Signal Output – Replaces the mechanical cable and delivers electronic speed data

• EFI Swap Compatible – Works with Ford EFI systems that require VSS input

• Direct Fit for Dana 20 – Plugs into the stock transfer case on 1966–77 Broncos

• Requires Digital or GPS Gauge – Must be used with a digital or GPS-enabled speedometer

Ditch the cable—this VSS plugs into your Dana 20 and sends speed data to your digital speedo or EFI system. A must for EFI swaps in 66–77 Broncos!
