Narrative:

Followed maintenance manual procedure with putting on new egt harness and taking off old egt harness clamp by clamp. Was not there on the closing of engine; so not sure as to why; or how; incident happened. Egt harness was in same position as old harness when I left aircraft. Old egt harness was not found in contact with engine reversers.
