Radio Installation I'm trying to install a new stereo and just need a layout so I can connect the wiring properly

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 :)

Hi, here are your factory wire colors/functions. Aftermarket stereos have a common set of colors, which should be in your installation diagram. The process is simplified if you purchase a wiring adapter for your vehicle. These are available for under $10 at most WALMARTs and auto parts stores or about any place that sells car stereos. In either case, I recommend you solder the connections or at least use crimp terminals. If you have any more questions, please let me know--I've done a lot of stereo installations.

following is the procedure. u can also check ehow for more details.

Twist the negative cable off the terminal on the vehicle battery, using an adjustable wrench.

Remove the factory issue stereo. Pry off the radio trim bezel with a flat head screwdriver. Remove the four bolts on each corner of the radio. Pull the radio out the dashboard. Unplug the thick black radio antenna cable. Disconnect the wire harnesses from the rear of the stereo. Place the old stereo to one side.

Prepare the dashboard for the new stereo. Fit the radio installation sleeve provided with the aftermarket stereo to the radio installation kit. Feed the sleeve through the portal of the radio installation kit and bend the tabs on the sides of the sleeve to secure it in place. Feed the audio wiring of the Jeep and the radio antenna cable through the portal of the assembly and slide the assembly into the dashboard. Secure it in place with the bolts removed earlier.

Wire the new stereo. Connect the wiring of the stereo to the audio wiring of the Patriot, using a custom wire harness adapter. Push the connections together until they snap into place and test the connection by tugging gently on either end.

Plug the radio antenna cable into the alloted port on the rear of the aftermarket head unit.

Slide the connected aftermarket stereo into the prepared housing in the Patriot's dashboard. Click it into place in the radio installation sleeve, taking care not to trap any wiring.

does this help, or do you need more?

I would get a stereo installation kit for your car from Auto Zone or a local car audio store. It will have the surround for the new stereo to fit where the old one was and a harness that you can wire the new stereo to and the harness will have a plug to match the stock radio plug.

I would check with a local auto stereo store for an installation kit, which should include a bracket for installing the new stereo, and a wiring harness to connect the new stereo with the car's existing wiring.

Forget it...go to a car stereo installation shop and buy a wiring harness for your car ($20-40) and you're done!
Good Luck
P.S. might as well buy a dash kit ($30) to make installing the radio simpler as well...if you DON'T have a car stereo shop nearby, order parts from crutchfield.com

If you disconnect the stereo, does the temp. display go back to working properly? Did you connect the stereo Illumination wire correctly? Are all the other stereo wires connected correctly? Double check what the wires in the aftermarket harness are supposed to be and don't just go by color.

Try radio shack, or stereo sales/installation place for ready to go plug adapter. For a few bucks, it saves headaches, and butchering the wiring in case you want to re-install old one later when trading in or selling the car.

You might save yourself a lot of headaches by stopping by a car stereo sales/installation place, and ask for wiring adapter harness. They should have an adapter plug that goes from your factory plugs to the new stereo. $10-$20 well spent. You may even find what you need at an auto parts store that sells stereos too, or radio shack.
