Connecting COMPUSHIFT to Digital Dashes and Speedometers

Regardless of what your gauge manufacturer tells you, you MUST NOT connect any wires to the the vehicle speed sensor (VSS) on your transmission other than the ones that come with you COMPUSHIFT controller harness. The COMPUSHIFT controller provides a speedometer output that will drive many different gauges and digital dashes. This wire should always be used instead of tapping into wires on the vehicle speed sensor.

Most Dakota Digital systems (include VHX, GRAFIX) have three connections for the vehicle speed sensor (VSS): SPD+, SPD-, and SPD SND.

• Connect the speedometer output from the COMPUSHIFT (purple/white) to the SPD SND input on the Dakota Digital system.

• DO NOT CONNECT THE SPD+ OR SPD- TO THE COMPUSHIFT CONTROLLER!

• Calibrate the speedometer per Dakota Digital instructions.
