INSTALLATION

1. Disconnect the negative battery cable.

2. Using the supplied Stainless Steel 1/8”NPT compression mount, mount the EGT
thermocouple as shown in Figure 2. Common locations for mounting the EGT
thermocouple are 1-2 inches from the exhaust port, 2-3 inches before the turbine
inlet, or in the header collector.

3. Connect the EGT thermocouple to the extension harness as shown in Figure 3.

4. Connect the 3-pin connector on the thermocouple extension harness to either the
EGT 1 location or EGT 2 location as shown above in Figure 1.

When using both thermocouples for comparison (bank 1 EGT and bank 2 EGT for
example), make sure to mount both thermocouples in a similar fashion (distance from
port, tip depth, tube diameter, etc) so the readings are not influenced by installation
differences.

Connecting the Thermocouple

Slide the supplied heat shrink onto the sensor cable. Connect the RED wire from the
thermocouple to the RED wire on the harness and the YELLOW wire from the
thermocouple to the YELLOW wire on the harness using the supplied 4-40 screws and
hex nuts. Make sure the connections are not touching. Center the heat shrink over the
connections and apply mild heat to the heat shrink until it shrinks over the connections.
See Figure 7.
