So a copy of your wiring diagrams will at least be kept on file for a time. I cant see how a company could refuse to give you a copy of the wiring diagram for work they did on a aircraft you own.
Most of the new avionics equipment being fitted today in light single/twin piston aircraft is done to generic manufacturer-produced STC installation manuals, so in most cases, there are no airframe-specific drawings produced.
Incidentally, I went to Brooklands Museum a few years ago and wandered round the Vickers Merchantman freighter. On board were a set of wiring manuals and they still contained my signed drawings for a new ADF system fitted in the mid 1980’s. So just sometimes there may be some data available!
