Most newer car stereo's come with a 16-pin harness.
These wires are shown on the left under "Standard."
If you follow the "Standard" wires across to the right, you will see the
wires you need to hook up to.
The red wire is the +12v ignition wire.
This supplies power to the stereo only when the key is turned.
The yellow wire is +12v constantly.
Regardless of whither the key is turned or not.
This supplies power to the radio to save memory
settings like time and what song was last played.
The black wire is the -12v ground wire.
This can be connected to your old harness or where the wire can have a clean secure
contact to the metal frame of the car.
The solid blue wire is the "Power Antenna" wire,
if you have a power antenna.
The blue wire with the white stripe is if you are going
to hook it up to an external amplifier.
The solid orange wire is for "Illumination."
Meaning the lights in your stereo.
The orange wire with a white stripe is a dimmer.
Some stereos allow the lights to dim when the headlights or parking lights are on.
The brown wire is for whats called "Phone Mute."
It lowers the sound of the stereo when sending or receiving calls.
Some older cars don't have certain features like external amplifier, dimmer,
or phone mute. In which case you wouldn't have any wires to hook up.
The last eight standard wires are speaker wires.
These are classified into colors.
The wires with the stripe going through it are all Negative wires.
The wires that are solid colors are the Positive wires.
It's important if you want to get the most out of your speakers to hook these up correctly.
Positive to the Positive terminal on the speaker, and Negative to the Negative.
Again looking to the right you will see the wires that you need to hook up to.
The ones that the manufacturer installed.
One thing to remember is age and heat can change the color of wires.
You can see here on this harness that there are no white wires.
They have all turned an off-yellow or cream color. The grey wire has turned to what looks more
like a brown. So what this means is that you need to take your time and go slow.
First hooking up the wires you are absolutely certain of. Then it will be easy to sort through the
ones that you may be a little confused on. As always, disconnect your battery before cutting or splicing any wires.
