DOC AIRBUS | AMM A320FEXHAUST GAS TEMPERATURE SYSTEM - DESCRIPTION AND OPERATION
** ON A/C NOT FOR ALL
1. General
The function of the two Exhaust Gas Temperature (EGT) harnesses (T48-left and T48-right) is to connect the eight EGT sensors to the two engine harnesses channel A and channel B.

2. Description
Main function of each harness is to supply four independent EGT signals from four EGT sensors to the Electronic Engine Control (EEC) (no internal averaging).
The harness, T48-left connects the EGT sensors 1, 8, 7 and 6 to the EEC channel A.
The harness, T48-right connects the EGT sensors 2, 3, 4 and 5 to the EEC channel B.
The two EGT harnesses are routed and mounted on the core area engine external case.
The two EGT harnesses are thermocouple cables.
Each EGT harness is consists of four independent pairs of conductors (Kp/Kn) each dedicated to an EGT sensor. The EGT harness sensor side ends with Kp and Kn lugs with captive self-locking nuts while the other end is equipped with a connector.
