    Wouldn't you also need to buy a different screen bezel since there wouldn't be a hole and a light indicator for the webcam?

    Probably but it doesnt matter. I could just drill some holes. My question is would there be a connection on the screen or the motherboard for the cam and would it work.

    Erik is usually really good at answering these types of questions. Hopefully he sees this along with others that might be able to answer that for you.

    I bought a T420 without webcam from Lenovo Outlet last year. It turned out that the screen bezel from my machine had a camera hole, it was just covered by a black plastic strip.

    Then I was lucky to snatch an 'empty' T420i screen assembly without LCD on ebay, and transferred its camera into my machine. All I needed was the camera board itself and the covering plastic strip which has two transparent spots for the camera's lens and LED.

    So I don't think they have two different bezel versions in stock for the T420, but only different cover strips.

    The cable is already there, and it powers multiple components. It was attached to a small circuit board identical in size and shape to the webcam board. This board is not just an empty place holder, but has a couple small ICs on it. I'd guess it terminates the cable electrically. You basically have to exchange that board with the webcam.

    The cable by the way originates from somewhere on the system board. It branches at the display bottom to power the LED board, and then goes all the way around the LCD panel to the top, where it branches again to the webcam board and the Thinklight. The Thinklight is actually firmly attached to one of the branch ends.
