I removed my console to have another radio installed and noticed a disconnected blue/yellow/green wire harness (see attached) Can someone tell me what it may connect to?

Also, in the picture - above the wire harness described above is a black connector with a dark brown wire attached to it from the left and 2 dark brown wires attached to the right side. I noticed one of the dark brown wires goes to another harness on the right, however the other dark brown wire is cut - I hope someone is familiar with this one also as to where it may have originally been connected. I have an overall wire diagram but just cannot make "light" of these connections!!!!

Thanks in advance!!! (77 Cutlass)
