Install a Car Stereo Head Unit

Does your old head unit (stereo) have a cassette player only? Do you want to replace it? Well, read this to learn how to install!

Steps

  1. DISCONNECT THE NEGATIVE TERMINAL ON YOUR BATTERY!
    • For an old stock stereo, you may have to remove the dash or certain parts of it to access the stereo. Do that by locating screws and bolts and taking them off. Make sure to keep them in a safe place.
    • Insert DIN tools into each slot on the stereo behind the faceplate for an aftermarket stereo,. Slide the whole stereo out.
  2. Disconnect the antenna wiring (The wire with the big metal tip)and the stereo head unit wiring (wire harness).
  3. Reconnect the antenna into your new stereo.
  4. Use butt connectors and wire crimps to connect the stock wire harness with a car specific one that is sold separately. The color of the wires on each harness should match up, if not do connect only the matching ones...
    • these are the color codes of the wires:
    • +Red..............12v ignition
    • +Yellow...........12v battery
    • -Black............Ground
    • +Blue.............Power antenna
    • +Blue/white.......Remote turn on
    • Orange...........Dashlight/dimmer

  5. Reconnect the negative terminal on your battery and see if it works.
