The Cable-X is the easy, cost-efficient way to operate your stock mechanical speedometer with a transmission equipped with a vehicle speed sensor. The Cable-X is basically a universal adapter that will pick up the electronic speedometer signal and will operate the cable driven speedometer to the corresponding speed. It’s a snap to install with only three wires – hot, ground and signal. No costly installation of drive gears or long messy cables to deal with. Don’t settle for anything less than the original, the Cable X.
