Colors could be slightly different as I just did a google search for Sony Harness but start off by disconnecting your subs and stuff, like you were just freshly installing the headunit only working with the headunit harness to car harness. Now 4 pairs of those wires are gonna be for their respective speakers, but make sure [remember colors may be slightly different] Yellow is your constant 12v power so make sure you got it into whatever the constant is on your car's harness, Red is the Accessory/Switched Power, make sure this is also connect to its respective wire from the cars harness, finally take the Black ground and either connect it to the black ground wire or [in most cases] just find a good metal ground source. Check a few places just to be sure your current ground source doesnt just suck. In some cases if you dont have the antenna plugged in to the head unit it wont turn on (as thats also a ground), i've experienced this before. After you've got the unit working, then plug in the rest of your outputs and such. I'm not familiar with that head unit but i had one where the connection to the faceplate was a little lose and would cut off hitting big bumps so after you think you got your wiring right, give the faceplate a light push in to be sure its got a proper connection. OH and yes you said there was a fuse in the back of it somewhere? Def check that first lol
You can always take out the head unit and try running a wire from the Constant and Switched pins to the positive terminal of battery and run Ground to the negative terminal to verify the head unit actually works. That should narrow it down to a wiring problem somewhere. If it doesn't suppose it might be the fuse in the head unit or its dead from some other reason...
