the Six-Gun harness with the supplied

insulated.

the vehicles batteries.
NOTE: Once the Six-Gun Diesel 
Tuner is powered up at key-on, it 
will ‘learn’ that a thermocouple 
is installed and automatically 
enable the EGT limiting function. 
If the thermocouple is removed 
after being installed and run on the 
vehicle, the Six-Gun Diesel Tuner will 
assume that the sensor or connection 
has gone bad, and cease adding 
power while triggering the [2,3] 
diagnostic code (see Trouble Shooting 
Section 8). To ensure that the Six-
Gun Diesel Tuner operates properly 
after removing a previously installed 
thermocouple, see the ‘Clearing 
Learned Information’ Section 9. EGT 
limiting will not be operational 
and excessive EGTs may develop 
at higher power levels.
