Narrative:

During a main engine control change on the #1 engine on air carrier X; the variable stator vane cable needed to be changed. A new cable was ordered and put at the aircraft for the oncoming shift to install. It was discovered later that this cable was the wrong part number for this aircraft but only on the #1 engine -- it's ok for the #2 engine.
