Years ago when I was 15 and retarded I cut the stock radio harness out, but only the electrical connections surprisingly. My stereo has yellow, black, and red wires while my stereo connections are orange, orange and brown, yellow, and black. Yellow should be hot all the time so that the radio can store stations and whatnot, correct? Orange should be what? Hot all the time? Orange and brown should be ignition hot? The problem is, none of them seem to be ignition hot, and I don't like the stereo having power all the time. So what is supposed to go where?
