What is I/O Board Cable Purpose?

Hey iFixIt Community!

I am curious about this cable: MacBook Air 13" (Mid 2013 through Early 2015) I/O Board Cable

Can anyone list exactly what type of I/O it is for? I've seen the same piece listed as an "Audio Power Cable".

At this point I'm guessing data IO as well as Audio. Would be great for a confirmation. Thanks!

I am looking to replace this cable since I have a broken one. MacBook still works but no audio. Thank you.

The cable bridges MLB and LIO board over the fan. There are data lines for lid sensor, audio codec, USB and speaker on it.

Does it have anything to do with the charging indicator on the MagSafe adapter?
