I need some information on the wiring on this amp. There are four harnesses attached. A gray,green,black,and brown. I tried hooking up a loc based on the 2017 pic but I couldn't get anywhere. Does anyone know what these wires are.

Thanks this highlighted an error I made, for a system like this I have to disable the Bose noise cancelling do you happen to have access to what wires these are so I can cut them? I belive it is two if i remember right.

Post a picture of the plugs. I do not know the wire color but will be able to point it out.
