Fixing stereo wiring (Page 1/1) Lowerit DEC 01, 10:25 PM I'm returning my fiero to the stock radio and had some questions about wiring. The car previously had a pioneer deck installed by me sometime around 2000. Sadly the original harness was cut, thankfully I have a replacement Metra stock harness I'm in the midst of putting in. I just wanted to clarify some wiring colors after spending time searching the forum. Fiero Speakers RR + DK Blue RR - LTBlue LR + Brown LR – Yellow LF + Tan LF – LT gray RF + LTGrn RF – DrkGRN 12V Constant ORANGE 12V Switched ? Ground Black Remaining unknown wires 2 Pink wires 1 yellow and black 1 gray and black It appears as though the installer pulled a switched 12V wire right from the fuse block, but I'm not keen on this if I can avoid it. I'm going to put a modern bluetooth stereo in , but want to start with a stock harness and make a proper adapter - Hence the desire to return it to stock. Thanks!
