If the VSS wire is not hooked up, the navigation system will not realize that the car is moving at all, and will be unable to track position. Ford Motor Company now has Wire Terminal Repair kits available to allow replacement of damaged or corroded terminals in a connector. (Don’t substitute the tachometer signal wire for the VSS wire - the tach signal wire sends pulses as long as the engine is running, even when the car is sitting still.) The VSS wire sends a series of pulses (from 800 to just over 1,000 per mile) only when the vehicle is in motion. Your vehicle’s cruise control uses the VSS wire to determine the vehicle’s speed - it serves the same function for the navigation system.
