I have taken the unit apart to get this information and just chopped off the plug since I did not have a suitable connector for it.  The wires into the plug are all coloured as above so you can apply 24v between the Black wire (+ve) and red or yellow (-ve).  The switch is not connected inside the unit but is used to tell the scanner to turn on the 24v.  I joined the Black and Brown wires together and applied 24v to the Orange (+ve) and Red+Yellow (-ve) so the switch now works.
