No BluTooth after Battery and Speaker replacement

Greetings. Just did a battery and speaker replacement - had to do the speaker reaplcement twice since they sent bad parts the first time. This meant that I had to basically disassemble and reassemble my mac twice - including removal of the motherboard etc.

The first time I put it together and eveythign was fine. Now, evernthing seems to be working, but I get no connectivity on blutooth. I don’t seem to see a specific cable for blutooth. I’m trying to figure out what I might be missing. Is it one of the antennas on the airport card? I know I had a lot of trouble reconnecting the middle one.

Thank you!
