3. LC-1 Cable connections:
A. Interface and power cables with 6 stripped ends*:
a. Red 12V supply
b. Blue Heater Ground
c. White System Ground
d. Yellow Analog out 1
e. Brown Analog out 2
f. Black Calibration wire
B. Serial In connection, 2.5mm stereo (female) marked as IN
C. Serial Out connection, 2.5 mm stereo (female) marked as OUT.
3.1 If you have an LC-1 with only 7 stripped ends the wiring is as follows:
a. Red 12V supply
b. Blue Heater Ground
c. White System Ground
d. Yellow Analog out 1
e. Brown Analog out 2
f. Green Analog Ground
g. Black Calibration wire
4. Connect the RED wire to a switched 12V source in your car. A switched 12V source
goes on as soon as the ignition on the car is on. Make sure the connection is fused with a
minimum fuse size of 5A.
5. The BLUE and WHITE wires should all be grounded to the same ground source.
Optimally, these (and any other MTS device ground) will be soldered to the same lug, and
connected to a single point. When this isn’t possible, connect each one to a separate lug,
and attach in close proximity. Multiple lugs on the same bolt is not optimal, and can result in
unwanted signal “noise.” When possible, soldering is always better than crimping. Please
see chapter for more information on Electrical Grounding Concerns.
6. Optionally, the YELLOW (Analog out 1) and/or BROWN (Analog out 2) can be connected
to the analog inputs of other devices such as data loggers, ECUs, or gauges. If either one or
both of these wires are not being used isolate and tape the wire(s) out of the way. The default
analog outputs are as follows: Analog output one is 1.1V = 14 AFR and .1V = 15 AFR. This is
a simulated narrowband signal. Analog output two is setup as 0V = 7.35 AFR and 5V = 22.39
AFR. Note: The LC-1’s heater ground and system ground wires should share the same
grounding location of the analog input’s ground. Refer to chapter 2.2 for recommended
wiring schematics.
7. Optionally connect a momentary push-button switch between ground and the BLACK
calibration wire. Please refer to section 2.1.
Note: The use of the calibration wire is not necessary if the LC-1 is connected to Innovate
Motorsports’ XD-16 digital gauge. If the wire is not are not being used, isolate and tape the
wire out of the way.
8. Optionally connect a indication LED (1.2-2.2V, 1-30mA is recommended) between the
calibration wire and ground.

Ive followed the instrucions above and t dosnt seam to be working the gauge just flashes 7.4 and I undersand that that's the system warming the sensor up but it never get warm and i also can not figure out how to wire the push button with the status led and getting it working
