Rotate Sprite based on Car Velocity Non GUI 3D Speedometer

I am using the Realistic Car Controller from the asset store. I have been trying to get a working speedometer that rotates a plane with the Needle sprite on it based on the velocity of the car. How would I do that? I know there have been a few questions about speedometers but I only found one that was a non GUI speedometer and the answer didnt help. The Needle is a sprite and not GUI. Any help would be much appreciated!!
