Part No. for top case for MacBook Pro 15"

History

I am trying to replace my top case. I bought a used one without keyboard and the part no is different. The one I purchased is 620-3739-A, which I was given to understand is the one for a 15" Macbook Pro 2.0GHz. The top case I already have is 620-3381-A. Both have different wiring. Does anyone know the correct part no this A1150? Thanks, Barrie Beckman

By different wiring, does one have a connection for an ambient light sensor?

Hello,

Thanks for your reply.

I think that may be an ambient light sensor. would that be the backlight to the keyboard? There is also another wire to the side with a tiny plastic block. Barrie
