My speedometer is pulsating when I am accelerating.

It runs from the back of the speedometer which is accessed by removing the instrument panel. The other end comes through the firewall and goes to the transmission at the Vehicle Speed Sensor, which sends a speed signal to the ECU for power steering and engine management. If you find an electrical connector on your transmission instead of a cable, then you have an electronic speeometer, your car is on the like for having one or not, then your issue is probably in the speedometer itself or the sender.
