Manual # 650300:C
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-A GAUGE
Install the new gauge 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, flat side down.
WIRING
Wiring the gauge will be slightly different than before as the bike doesn’t have provisions for the
new sensor. Use the supplied sensor and wiring to make a jumper harness from the original plug to the
new BOOST gauge.
*
DO NOT connect the factory connector direct to the gauge, use supplied wiring.
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. B
oth inputs 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 receives
+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.
