PART# MCL-3K-FUL

Thank you for purchasing the Dakota Digital MCL-3K-FUL gauge for your Harley Davidson Touring bike.
This gauge is designed to be a direct, plug in replacement for all touring models from 1996 and up. This
is part of a six gauge package for touring models so you can add additional gauges as you choose.

You must select the correct fuel level sensor in setup or the gauge will not read correctly. The

stock fuel sender for 1996-2007 models is the “10

10” setting, and “33

1010

33” for 2008 and up.

First read and familiarize yourself with all of the components and this manual. The first step is to
remove the seat and disconnect the negative side of the battery, as with any electronic install. Once the
battery is disconnected you are ready to start.

REMOVAL OF FACTORY GAUGES

Remove the outer fairing; this will vary from model to model, please follow the service manual to
expose the wiring and gauges. Don’t be alarmed by the amount of wires behind the fairing, this is a
direct plug in kit and these detailed instructions will guide you through it.

All of the small gauges, fuel, volts, oil, and air temp have two plugs. One is for illumination the
other is for the gauge power, ground, and sensor signal. The illumination harness, two pins (orange and
black wires), and will not be reused and can hang freely inside the fairing with the bulb removed, or can
be secured to the other gauge wires to clean things up. The three pin connector from the stock gauge will
be used to connect the new Dakota Digital MCL-3k gauge. Unplug connectors at the back of the gauge,
then remove the two 5/16” nuts holding the clamps onto each small gauge and remove the gauges.

WIRING

(+12V Key ON)

(This terminal connects to the
stock fuel level sensor)

The three tab connecter toward the bottom of the back side of the MCL-3K gauge is designed to
plug directly into the stock harness. This will provide the gauge power, ground, and sensor connection. If
the wiring harness plug is not available, wire according to the drawing on next page. Standard ¼” female
spade connectors can be used to make a connection to the gauge.

The second connector toward the top of the back side of the gauge is where the supplied
Switch/Dim harness connects. Both inputs are active high and are “triggered” when there is +12V on
either wire.

BLUE Wire (Dim Input)

The BLUE wire is used for optional night time dimming function. When this wire is held
high, +12V, the gauge will dim to about ½ brightness.

GREEN Wire (Switch Input)

The GREEN wire is used for a switch input for entering setup. This wire can be wired to a
momentary push button switch and the other side of the switch to +12V. The wire can
also be stripped back and touched to +12V to enter setup and then taped off once
complete.
