I'm trying to install a kenwood 7120 into my 04 4runner. I removed the factory head unit and now I am stuck. Does anyone have a radio wire diagram or anything that will help? There is just too many wires and the color codes do not match up..... I already have the tyto1 aftermarket amp wire for the JBL system. I just don't want to splice all the wires without knowing how they match up. I did a search and couldn't find anything. Thanks in advance!
