All will become quite clear once you remove all of the dashboard components.........
You will notice that the brake master cylinder and reservoir is held by a couple of bolts to the servo assembly, simply unbolt the one supplied on the second hand unit and disregard it. Do the same to your own master cylinder but leave the pipes connected and simply push it towards the screen so you can get the old servo out from its location Then once you have jiggled the new servo/ pedal box into position simply bolt your existing master cylinder to the replacement servo,,,,,,,,no need to get involved bleeding the brakes...
