If you are replacing a gauge in a set of Dakota Digital gauges, plug the small, white, two-pin
connector into the air pressure gauge just as it was on the other gauge you removed. If you are adding
this gauge to the set rather than replacing one (you will have a total of 5 small Dakota Digital gauges on
the bike) you will need to locate any one of the other BLUE and GREEN wires going to the other gauges
in the set, cut and splice into the new harness. Match BLUE to BLUE and GREEN to GREEN. If you are
installing multiple MCL-3K gauges without a Dakota Digital Speedometer, you can tie the GREEN wires
together and then to one switch. The same is true for the BLUE wire, wire all of them to one switch.
If you have an MCL-
3K Tachometer, it will actually serve as the dimming “switch”. The BLUE
wire on any of the MCL-3K Tachs will provide a +12V output for the dimming function. The gauge has a
light sensor behind the lens and when the ambient light is dim or low it will “turn on” the output and
12V to the BLUE wire. You will not need to wire in a toggle switch if you have an MCL-3K
tachometer and choose to wire it this way.
