SOURCE: Speaker replacement

They still follow the GM standard:

LF+ tan
LF- gray
RF+ light green
RF- dark green

LR+ brown
LR- yellow
RR+ dark blue
RR- light blue

Note that if you're looking for them behind the radio, some of the same colors may be used on other wires. The speaker wires should be placed side-by-side for each speaker.

Also, if you're replacing the factory radio, I highly recommend buying a wire harness adapter instead of cutting off the factory plug.

SOURCE: car stereo

its pretty simple, the remote wire is used to tell the amplifier that the cd player has came on. once the cd player has came on, the amp then comes on. simply take a light tester that has a sharp tip, turn the ignition until the cd player comes on, and start testing all of the wires. when you hit a wire in which the light tester says there is power flowing through it, turn the cd player off. if the light goes off with the cd player, you have found a wire that is suitable for a remote wire. dont know how to use a light tester? http://www.bcae1.com/testlite.htm

How do I fix the clock display on my 1999 Pontiac Sunfire?

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.

The oem stereo removal video is for the 2000 to 2005 Sunfire / Cavalier, but are the same or very similar procedures.

2004 sunfire ignition key wire does it have one/ instaling new radio only have constanyt 12 volt radio power on off button does not shut off do i use this wire and where does it go the ignition wire...

Hi, your factory Sunfire wire colors are pasted below. The yellow wire should be accessory. This should connect to the stereo's red power wire. The orange "always hot" wire should connect to the stereo yellow wire--this is only used to keep your station presets in memory. Please let me know if you have more questions, and thanks for using FixYa.

How to hook up a kdc-105 kenwood in a sunfire

There are 3 things you need to purchase for this install. 1) The factory spec install kit. 2) The factory spec additional wiring harness. 3) Antenna adapter.

Find the easied way to remove the plastic cowling around the radio and ac controls. Usually you can locate screws helping to retain the plastic dash parts. Be careful not to break the plastic dash by taking your time and looking over and over the part ofr connection hardware. Once you have located and removed all/if any screws, carefully pry out on the piece you are removing. There are often metal clips on the back of the piece that also help to retain the dash. Once that is removed, unbolt/unclip the factory stereo and slowly pull it out of the dash. Remove the factory harness from the backside of the factory stereo. DO NOT CUT THE HARNESS!! The wiring harness you have purchased is designed to plug and play into the factory harness. All you hae to do is color match the Kenwoods harness with the one you purchased. When wiring the two harnesses together use connectors **** a **** connectors, crimp connectors so forth and so on. If there is wiring you will not be using, take some electrical tape and tape the bare wire. We don't want a short. Once you are sure and have doubled checked that all the wiring is secure and matched, reverse the order of disassembly.

The plastic install kit should replace the factory radio size difference. Just remember to take the metal sleeve tha came with the kenwood and install it into the plastic install kit via the instructions provided. Slide the Aftermarket stereo into the sleeve you just installed. Then you are ready to make all the needed connections. Before you reassemble everything make sure to do a test run with your stereo. If all is well reassemble and jam on.
