***New nuts for the small gauges are included in the hardware pack DO NOT reuse the stock nuts for the
new gauges; they are not the same thread.
Once the gauge is removed, save the clamp as it will be reused with the new MCL gauge.
Remove the small gauge
with 5/16” wrench or nut driver Save Clamp, and reuse for install
INSTALLATION OF NEW MCL-3K-VLT GAUGE
Install the new gauge back into the fairing using the original clamp, along with the supplied nuts.
Be sure the alignment tab on the clamp lines up with the notches in the fairing when tightening the clamp
back up.
WIRING
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 and ground 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. Also note that the “SENDER”
terminal doesn’t need to be connected for the MCL-3K-VLT to function as it uses the “POWER” terminal
for its voltage reference.
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.
