Installing a aftermarket stereo

It appears to be that the radio clock display has malfunctioned, and is due for a replacement radio, which could be an aftermarket or oem radio, maybe found at a junk yard.

Tools required for oem replacement radio, torx keys set.

Before working on the radio or other electronics, disconnect the battery cables with 8mm wrench.

Replacing the oem radio is much easier, if you obtain oem radio, compared to aftermarket radio, due to being direct fit.

The radio is same for 1995 to 1999 Pontiac Sunfire and the Chevy Cavalier, regardless of sub models, such as SE,GT, VL,VLX,Z24. etc.

Parts needed for the the aftermarket radio install :Stereo assembly, stereo wiring harness adapter, radio antenna adapter, and dash install kit.wiring diagram for the wire colors / functions, along with tools, such as torx key set, screwdrivers,wire crimper, wire stripper, double ended wiring connectors, hair dryer.

You best bet, because of a warranty, is to have a professional shop install your stereo. But if you are like all of us guru's here, you like to get your hands dirty.

First you need to remove the dash around your factory stereo. Be patient here and try not to break any of the dash. You may need to remove screws and pop loose plastic retainers located on the backside of the dash.

Wire the after market stereo to the harness located below by maching the colors provided. Thank the stereo companies for making this simple. Use crimp connectors or solder your connections, which ever best suits you. Tape up any remaining wires with eectrical to minimize the chance of a short.

Take the metal sleeve provided by the sereo you choose and install it into the install kit located below. Once you have removed the factory stereo, test fit the install kit and attach any tabs neccessary provided by the kit.

Now take the aftermarket stereo and place into the sleeve you installe din the install kit until it clicks into its locks. Now, the harness you wired up earlier, plug it into the factory harness and then into you stereo. Hook up the antenna, you may need to purchase a antenna adapter. Now before you install the stereo, do a test run to make sure everything is working. Once you are content that it is all working, install the new stereo and then reverse the steps in removing the dash panel and stereo.
Below are pictures of the needed hardware:

you can purchase a wiring kit that plugs into existing factory wiring for about 20 bucks saves alot of time and trouble

Red is power to from ignition to cd deck
Yellow is direct power from battery to cd deck to hold the memory.
Black is ground
Blue is only needed if you are hooking up an amplifier.
I always suggest buying a wire harness quick connect system for $5, then you won't have to cut origional car wiring. If by chance you are taking the original wire route, then go to installer.com to find which wires on the car are for what.

What kind of stereo, probably a wiring problem.

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.

attach both power and illumination wires to constant on car wires.... only way to have switched power is connecting the switched/ignition wire to a fuse

are stereos known to be good. try buying wiring kit for use in your application.
