Not too sure what you're asking here.  But they are secured to the inside of the cover by a few bolts.  Remove the bolts and the wires will come free along with the stator assembly which is also secured to the cover with a few bolts.  When/if you transfer them to a new cover, bolts the stator assembly as well as the pieces holding the wires to the inside of the cover.  There is a rubber grommet that passes thru the alt./stator cover and I would put some high temp silicone sealant on the grommet to make sure it seals up and doesnt leak oil.  I did this same method when I replaced my cover a few weeks ago and still bone dry.
