1.4 – How to install the EGT thermocouple
The Exhaust Gas Thermocouple (EGT) has to be installed inside the exhaust
header pipe at a distance of approximately 5.9“ (150 mm) from the exhaust port.
The figure below shows the proper way to install the EGT thermocouple and the
installation wrapper.
It is recommended to insert the sensor between 25% and 50% inside the exhaust
gas header.
To correctly install the EGT thermocouple, please follow these instructions:
1. Make a 0.2” (5 mm) hole inside the exhaust header
2. Fix the metal wrapper to the exhaust header pipe in the hole you have
drilled. It is reminded that the pipe’s hole and the wrapper’s threaded nut
must be coaxial
3. Screw the EGT thermocouple in the wrapper’s nut and firmly fix it. Plug
the thermocouple’s male Mignon connector to the EGT input wire of the
“2 temperatures split cable”.
