Anyone have 2015 SS manual with harness information?

Anyone with a 2013 Camaro SS manual know which connector this is and the wires in it? It's to the left in picture of the x102 connection which is left and next to fuse box. Alldata isn't showing this connection under 2013 SS manual but the harness is definitely 2013-2015 SS manual ls3 harness.

My car isn't here so I can't go physically check, but I think that is the X103 body harness extension.
If you can trace one of it's wires back to the fuse box connector and tell me which connection it is and which fusebox connector, I can tell you what it is.

I have a wiring database I made when I rewired my car.

ETA: It isn't the X103. The connector you show has 5 spots and the X103 has 14.

Let me know where the wires go and the color of the wires and i'll try to figure it out. I can picture that connector in my car but can't remember what it is called.

It's connector X111. On the engine side of harness.
I found the correlated wires for my year. Two of the wires are different. High speed GMLAN serial data wires. Pretty much my computer comms.
What I can't figure out is how to get them in circuit with their respective wires from connection X104 from the BCM.
I can find my wires on the wire diagrams. But I'm easily lost after trying to find how to pin the data wires in through the fuse box.
Anyone have hints or time to explain?
