Narrative:
While working on other cabin systems on aircraft xyz, I noticed wire sleeve for power port wiring abraded near right overwing exit (in seat track). I obtained MEL 25-32-xzxz from maintenance control. Upon reading this MEL afterward, my attention was brought to the activation/implementation date at the top of the page in our MEL book. The date is apr/xa/00. This placard becomes legal on that date. We are in violation of policy issuing this MEL.
