Narrative:
While working on an 'a' check on aircraft xyz, I found a conflict with the work pack instructions regarding emergency exit sign confign and the maintenance manuals. A detailed review shows that the wiring manual, ipc (illustrated parts catalog), 'a' check work pack and eco (engineering change order) XXXV can't agree on the required lens for the G4-G5 galley walls. This is the galley between business class and coach class. Some discussion has occurred previously to no resolve, but I obtained a copy of the eco (engineering change order) this date and chose to configure aircraft xyz per this paperwork.
