Dave,

You will need to go buy a wiring harness adapter from your local Walmart (usually cheapest there) or Local Electronics place (ie Best Buy). The wire harness that goes out from the radio goes into the Adapter and the adapter plugs into the car harnesses. Also these Adapters come with the wiring diagrams for your vehicle. They typically run 10 - 15 bucks depending on where you get them. Thanks for using FixYa!

Sincerely,

JC

I have an 02 ford explorer, the previous owner had a custom sound system installed. He took allof trhe custom speakers and amps out but left the stereo in,but it does'nt play. the stereo work ands powers...


sounds the like the vehicle had an oem amplifier that was removed, most after market stereo installers will trace the speakers wires individually by continuity to by pass the factory amplifier and wire the new head unit to the vehicles speakers, if the harness has been spliced or factory amp removed, you will need to check if the amplifier still exists (usually under passenger rear seat sometimes located in trunk area) and see if the harness has been bypassed. if so you will have to reconnect the harness by color code in order to use the factory head unit

I was installing an after market Pioneer CD Player into a 1993 Suzuki Swift. I installed it with all the right wiring and everything was working fine with the stereo. Once I turned the headlights on, that...


The adapter harness for the radio is probably not wired correctly. I'll bet you also have no tail lights. You probably wired the harness so that the illumination circuit for the factory radio is wired to the wrong terminal of the new radio, thus the problem occuring when you turned on the headlamp switch. I have seen this many times when someone is trying to wire a radio adapter harness without having access to the factory wiring harness diagrams for the vehicle...the wire colors on the adapter harnesses don't allways match the wire colors of the factory harnesses. You need to know which wire is which and wire the correct wires together regardless of what color they may be. If you wired it simply by the wire colors, it most likely is not correct.
If you are lucky, it only blew the fuse for the tail/dash lamps. It is possible that you now have some serious vehicle wiring harness damage caused by the short circuit that was created.
I would disconnect the new radio and get the car fixed first. Then you need to find out which of the wires in the factory harness is for the illumination circuit and make sure that nothing is connected to it on the adapter harness. Most aftermarket radio/stereo systems do not use this circuit at all.

How can i replace the manufacture radio in my car and replace it with aftermarket car stereo


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:

Want To Install New Stereo


You need to remove the front face on the dashboard...either you can "feel" your way through this, or you can get a basic manual like haynes that contains instructions. Most radios have accessory packages available that consist of an adapter harness and face plate which will make the job go a bit easier.R&R instructiona are not complicated but too long to write out.
Good luck!

Replace factory radio on 2002 yukon xl


all you gotta do is carfully pry the dash panel off (prying from the far left end is easiest) completely remove panel. then there are 2 clips that hold the factory sterio in place. push on the both clips while pulling the radio out. simply disconnect the wiring harness from the back of the radio. using an adapter avaliable at your local radio shop (scosche p/n gm02, mdarb and gm1483b) wiring harness, dash install kit, and antenna adapter. then simply match the colors on the new radio's harness to the adapter harness, crimping each connection with a "but plug". then simply follow the instructions included with the dash install kit to assemble the kit.connect the antenna adapter to radio, plug in all cables. test to see if everything works properly before the final install. install sterio into dash install kit, re installing kit where origional radio was. then simply put the panel back in its place by firmly pushing on it untill it snaps into place. then enjoy your new radio!
