Need Aftermarket Radio Wire Harness Adapter for 1998 Toyato Camry Sedan

The stereo pin layout can be obtained from the car dealership, also a repair manual should have the stereo wiring harness layout in it , the stereo harness adapter for installing non oem stereo, found at the local auto parts store will come with the wiring layout, wires are color coded too, sometimes the stereo harness or stereo harness adapter will have small writing on the wires itself, showing you what that wire is for, and where it should connect.

Basically it comes down to, obtaining the stereo wiring layout, read the description on the wires, and properly connect them together, then solder the wires or crimp them, I like to solder mine with soldering wire for electronics, and put shrink tubes to protect the wires, put the shrink tubes on the wires before soldering together, and ensure the shrink tube is the proper size awg wire gauge.

You will also need, aftermarket face adapter kit and antenna adapter, if installing aftermarket stereo.

Hope this helps and enjoy the stereo :)

Did you install an aftermarket radio? Did it have a wiring harness adapter kit for the installation? If so, the adapter should have made the install a plug-and-play operation. If not, and you sppliced wires into the vehicle's dashboard wiring harness, you could have cut into something you shouldn't have. More than likely, during the removal of the old radio and installation of the new one, you inadvertently disconnected a non-radio plug/jack on the dashboard wiring harness. If someone else did the work, take it back to them and ask them to make it right.

As in aftermarket like a Sony or Kenwood or..???? Yes.
The easiest way to install one is to get an installation kit. One that has a bracket/face that fills the hole in the dash and the new radio sits in and a wire harness. The harness makes things so simple. You don't need to know what wire color is what. The cars factory harness plugs right in and the new radio wires will be the same color on the harness.

Your aftermarket radio should have color-coded wires which identifies power, ground, speakers, etc. most depaetment stores carry a radio harness adapter kit. This will connect to your radio's exact color coded wires, and will plug right in to your factory's wiring plug. And don't forget electrical tape.

Most aftermarket pioneer cd/radio decks have the electrical connector for the antenna that I've seen.

Is this a cd only deck, or does it have radio functions?

Did you use a new harness wiring adapter to get the pioneer radio to work with the old harness?
There should be a color coded set of wires for the power antenna on that. And, then the Pioneer radio should have wires that were labeled for the power antenna.

Depending on what radio you are putting in, You may need an adapter pigtail. Read the directions closely.

Power for memory, power when key on or accesories,etc, then all the speaker wires. Have you stopped at a stereo sales place, or autoparts place and asked for an adapter harness to go from your vehicle to an aftermarket stereo? It will make it much easier, much cleaner in case of removal later & will probably save a big headache too.

If your installing a stock radio/cd player from another Dodge the wiring plug is the same and will fit.If your installing a aftermarket radio/cd player(JVC,Pioneer,etc)you will need to buy a adapter plug that wires up to the radio and is a direct fit to your factory wire harness,so your not cutting your wires.When you buy the adapter plug it comes with a wire diagram of which wire is what.Your aftermarket radio should have a diagram also,either on it or in the manual.Hope this helps you.
