Your speedometer on your 1995 Dodge caravan stopped working how do you find the cable to replace it?

There is no speedometer cable on a 1995 caravan. it is done by a speed sensor on the transmission and digtal data is sent to the computer and the computer then sends the signal to the speedometer. This is the case even when the speedometer looks analog. Likely a bad speedometer is the cause if it does not move as the speed sensor is used for other functions and would trip the "check engine" light if it was bad. the speedometer is part of the instrument cluster and likely you would need to change the whole thing.
