Narrative:

The aircraft had maintenance done for the captain's system annunciator panel. When we were in cruise flight; the center fuel tanks were empty and the correct master caution warning light illuminated. On the captain's system annunciator panel; we however saw a 'doors' annunciation in place of the expected 'fuel' annunciation. The captain's annunciator panel had incorrectly been replaced with a first officer annunciator panel three days prior.maintenance had installed the wrong part. Several pilots missed the error on previous days. The lights were working; it can easily be missed that the annunciations were wrong. Maintenance supervisors need to emphasize attention to detail to their mechanics. Pilots; including myself; need to look more carefully at the annunciations; in this case during multiple 'recall' checks.
