G3 Air/Fuel Gauge 
 LC-1 Quick Start Guide 
 
 
1.  Wire the LC-1 per the unit’s instructions 
2.  Connect the gauge’s BROWN wire to a permanent/constant 
12 volt source.  
3.  Connect the gauge’s BLACK ground wire at the LC-1’s 
White ground point. This ground point should ideally be an 
engine block ground. 
4.  Connect the gauge’s GREEN wire to the LC-1’s Brown 
analog output 2. The gauge is setup to work with the LC-1’s 
analog output 2 factory default setting of 0v = 7.35 A/F and 
5v = 22.39 A/F.  
5.  Connect the gauge’s  WHITE and BLUE wires to a switched 
12 volt source (ignition switched).  
 
Optional Tip/Trick 
(requires connection of LC-1 to PC) 
The LC-1 can be programmed to output specific voltages during 
warm-up and error conditions. This can be done by connecting 
the LC-1 to the computer and launching LM Programmer. The 
warm-up and error condition options for the analog output are 
under the Advanced… settings. For example, if you setup the 
error condition at 5V your gauge will display full lean if any 
problem arises. Please refer to chapter 6.5.1 in the LC-1 manual 
for further information.

G3 Air/Fuel Gauge 
LM-1 Quick Start Guide 
 
The LM-1’s analog output cable has three ends: Red wire 
is analog output 1, White wire is analog output 2, and the 
remaining wire is the ground. In these instructions we 
will be using the white and ground wires. 
 
1.  Connect the gauge’s BROWN wire to a permanent/constant 12 volt 
source.  
2.  Connect the gauge’s BLACK ground wire to the LM-1’s analog 
output wire’s ground.  
3.  Connect the gauge’s GREEN wire to the white analog output wire.  
4.  Connect the gauge’s  WHITE and BLUE wires to a switched 
12 volt source (ignition switched). 
 
 
5.  Connect the LM-1 to the computer and launch LM Programmer. 
Setup analog output 2 as 0v = 7.35 A/F and 5v = 22.39 A/F. Lastly 
click on the “Program” button.
