WIRING
First locate your speedometer connectors in the factory wiring harness that were unplugged from the original
speed gauge. The wires needed for the Dakota Digital speedometer should all be found here. The factory connector
can be cut off or the new wires can be spliced into the harness. Not all wires may be present on all years or models.
VSS wiring
For cable driven speedometers, you will also need to wire in a speed sensor. If you have provisions for a
transmission mounted sender, use Dakota Digital SEN-1017. If not, use Dakota Digital SEN-1011; a cable driven
speed sensor. The following table shows the wiring for each sensor type.

Gray White Green White
White/Red not used Red Red
If you are using the cable driven adaptor, you will also need to pull the speedometer cable from the front wheel
and replace the cable nut with the supplied cable nut so your speedometer cable will thread onto the new sender. You
have to take the cable off at the wheel so the nut can slide down and off the end of the cable and allow the new nut to
slide on. After the nut has been replaced, the speedometer cable can be connected back to the wheel and also to the
sender. Secure the sender with a zip tie and make sure there is no binding in the cable and that the cable has engaged
fully into the sender.
Switch wiring
Using either the factory trip reset switch or the supplied push button switch, connect one wire from the switch to
the MCL-30K-SPD green wire. The other wire from the switch should be spliced into the MCL-30K-SPD white/red wire.
The white/red wire may be shared with the function switch and the SEN-1017 or stock speed sensor. If additional
MCL-3K or MCL-30K-TCH gauges are being installed, the green wires on all of the gauges can be connected together
to share the function switch.
Night dimming
The BLUE wire in the MCL-30K-SPD harness controls the dimming circuit. When this wire receives +12 volts,
the gauge will dim to 50% intensity. This wire can be connected to a toggle switch, or to a Dakota Digital MCL-30K-TCH
(the tachometer has a sensor that activates the dimming feature when ambient light is low).
