I intrepret you message to mean that you are looking for the speed pulse which comes from the driveshaft. It is one of the 5 wires connected to the black plug for the radio. The 5 wires are as follows.

(May not be in order)

1. Ground.
2. Speed pulse.
3. Battery.
4. Ignition or accessory.
5. Illumination.
