Sorry for the delay! The 620-3381-A upper case is for an A1150 model MBP 15". The Bluetooth board for the A1150 is in the lower case near the hard drive. The 620-3739-A upper case is for an A1211 model MBP 15". The Bluetooth board for this model was moved up to be attached to the upper case. The extra wires you see are for Bluetooth. As far as I know, the parts are also incompatible due to connector location and size. Your best bet is to return the part and purchase one from a trusted vendor that ensures compatibility. Sorry for the bad news!
