this is the best way to work it. But one from an omega b with as much wires attached as possible. You also need the metal bracket that is glued to thee window of the omega. On the calibra it is a different set up, the mirror glues direct to the window.
You have 2 options for wiring it up. You can 1st tap into the power supply for the passenger vanity mirror or 2nd make new wiring from the battery to it but remembering to fuse it. There is also a wire that must go from the mirror to the gearstick area i think it is as a wire needs to be wired into the sensor that sends the signal to the reverse lights.
I decided not to fit mine for one reason only and that was when held up in place i though it looked a bit big and daft looking. So in the neext week mine will be going onto ebay.
Hope this helps some.
