I am installing a LOC and I have tried to research this the best I could, only the information that I found, doesn't seem to match up. As of right now I have my power, RCA's, and remote wires run. The stock HU is out and there was 3 harnesses that was plugged into it. Right now I am trying to determine which wire and which harness is the LR+, LR-, RR+, and RR-. Also from what I have found during my research, I need to connect the remote to the gray wire, which I only see one from all 3 harnesses. If someone could tell what wire is what or point me in the right direction, it would be much appreciated. I found this site, that I thought was gonna help, but I can't find some of the colors on any of the harnesses and there are some harnesses with the same colors, so I don't know which to go with. http://www.the12volt.com/...sp?TID=94043&get=last I have a 2007 tC with the base grade HU!

 

its the biggest wiring harness. the others are for the ipod/aux

 

Ok well I only have the aux and not the ipod so I am not sure what the third is, maybe the audio controls on the steering wheel but, do you know which color means what?

 

i dont know off the top of my head but just tap into the gray and your done

 

I know that the gray wire is for the remote, but my major concern now is I don't know which wires are mt rear speakers and which are positive and negative.
