phone cable on lappy

[CHARLIEBORG]

I'm replacing the motherboard in a laptop, Dell Inspiron 5160. Coke spill... Any way I got it all hooked up except the cable in the case that runs from the phone plug. Where on the motherboard does the other end hook too? I looked every where for some thing that looks like it was ment for it, but no go? Got any ideas? I tried looking for a diagram og the wiring, but no luck on that either.
