Do you need a wire for the speed sensor?
Click to expand… Hooking to the vehicle speed sensor (VSS) is only necessary if the stereo unit also has built in navigation software that uses it. Without built in navigation there will be no wire for the VSS.
Where is my vehicle speed sensor ( VSS ) wire located for?
Where is my Vehicle Speed Sensor (VSS) Wire Located for Radio Installation? When you remove your OEM radio, there are 4 plugs that plug into the radio. Only 2 of the 4 connectors are used with your new aftermarket radio which are the 2 connectors with the larger size pins.
How is a speedometer cable connected to a transmission?
Most vehicles use a manual cable hooked to the transmission case to decipher the rpm (revolutions per minute) signal. The speedometer cable, although simple in design, breaks down like any other component. Speedometer cables fail from lack of lubrication, impact, wear and cable breakage.
How is the VSS wire used in cruise control?
Your vehicle’s cruise control uses the VSS wire to determine the vehicle’s speed — it serves the same function for the navigation system. (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.)
What kind of connectors do you need for a car navigation system?
Here is our step-by-step guide to using Posi-Tap connectors when you need to tap into a wire in your vehicle. Each Posi-Tap wire connector splits into three separate pieces: large cap (tap end), barrel with conductor point, and small cap (accessory end).
Where is my vehicle speed sensor wire located for?
The other 2 are not used but the VSS wire is the brown wire located on the larger of the 2 connectors not being used. In addition to the standard power and ground leads, remote-mount navigation (and even some in-dash units) systems connect to a vehicle’s Vehicle Speed Sensor (VSS) wire.
Do you need a speed sensor wire for Your Stereo?

How do you install a car navigation system?
Insert the tap wire into the large cap and hand tighten into the barrel. The conductor point pierces the tapped wire without compromising its conductive integrity. Slide the stripped end of the accessory wire through the small cap.
