A line mechanic reports an engineering order (east/O) issued by his air carrier for their B757's and airbus fleet is too vague to be accomplished correctly by all the different mechanics; in all the different stations; in all the different states. The east/O required mechanics to coil and stow specific wires associated with the passenger air to ground airfone telephone system.

Narrative:
This engineering order (east/O) on the B757-200 and airbus fleets (and possibly other fleets); is too vague to assume that it is being accomplished correctly by all the different mechanics; in all the different stations; in all the different states. The B757 east/O; line 2 says to 'coil and stow' the wires; referencing wiring diagram manual (wdm) chapter 23-19-01 and standard wiring practices manual (swpm). Well; the swpm is about a ten thousand page document and it took me about an hour to find the pertinent pages. I would bet that all the different accomplishing amts have not been as determined or as lucky as me to find the correct pages. As far as the airbus east/O; referring me to the electrical standards practices manual (espm) chapter 20-33-10; this is a one page; three line document telling me to look in the chapters that follow; and I am yet to find any positively correct direction. It seems that instead of having hundreds of mechanics wasting at least an hour researching this and probably coming up with different procedures to accomplish this east/O; that simply referencing the chapter; page and paragraph would make this simpler and have a better rate of success of accomplishing this correctly.
