You have an electronic speed sensor.

It is a 3 wire plug, verify you have power (5V) and a ground to that connector with the key on RUNII. Also, with the wheels spinning you should see a signal from the remaining wire. If there is no signal the sensor is bad.

If the signal is good and circuity leading to the cluster is fine, you have a faulty cluster.

Hope this helps.
