Ok so how does it measure how fast i'm going if all their is, is the wheel with no wires or anything? Is thier something suppose to be connected with it? :banghead::banghead::banghead::banghead::banghead:

A magnet my friend! There's a magnet in the paddle wheel. Every time it goes around it passes a coil in the holder. That sends a signal back to the speedo how many RPMs it's turning which is translated into MPH
