Ok, relax. The purpose of the harness is to wire you radio to it, then be able to plug into the factory harness without cutting wires. Let's start from scratch. The harness you have should have all the wires you need IF you told the retailer all the specifications of your vehicle. Basically the harness should have a positive, negative, switched power, and speakers (4 sets). Speaker wires are generally grey, green, white, and purple. Constant power is red, switched power is yellow, and ground is black. However, you unit may have other wires coming off of it, such as remote turn on (usually blue), RCA outputs, and will have an antenna jack that you may need an adaptor for. Sometimes factory harnesses have two plugs. Sometimes they are not required for the radio to be functional (it may be the output and return for an external amplifier that you are currently bypassing). So follow the instructions on the package. Don't feel like you have to be stuck in your car to hook your radio to the harness either. Hope this helps.

I need to know the wire color code for 2004 Chevy express van. I want to hook up new radio, but not sure how to hook them up to new radio.

I recommend getting a wiring harness. If you "hardwire" this radio, you risk frying your electronics. Unless you want to spend about $2500 for new vehicle electronics. Good luck

I have a used unit, need instructions on how to hook it up to a caddy 1995 factory am/fm radio

Are we talking a new deck/stereo or new speakers/subs?
A new deck will require a wiring harness (cheap at walmart or local auto place) and this will come with a set of directions and wiring diagram for your make/model vehicle.
Subs/Speakers can be wired into a stock AM/FM radio (though I have no idea why anyone would want to do this) fairly simply, The wiring diagram will be printed on one side of your stock radio letting you know where to attach the 12v constant, the remote wire, and the speaker wires.

I just installed a new deck but no sounds or feedback from speakers what am I missing

You need to answer a few questions first. Do you have a factory or aftermarket amp? Did you use tape or crimps to attach the harnesses together? Did you use the proper harness? Is the head unit new or used? Check the fuse(s) in the back of the head unit. Then check your wire connections. Check that they are hooked up to the right colors and they are solid.

I would like 2 connect mazda wire harness to nextar ncd50.HOW CAN I CONNECT that can u plz explain me

It depends on if you have an after market wiring harness that adapts the factory harness to the new cd player, or trying to hard wire into the factory wires in the car. First off, if you don't have a aftermarket harness, i would strongly suggest picking one up from Wal-Mart or automotive store, they are around $20 and save a lot of time. If hooking up this way, you just have to match the color wires to the same color of wires on the cd player. Red to Red, which is power, Yellow to Yellow which is Constant power, Black to Black which is Ground, Blue is only used when you have a power antenna that goes up when the car is turned on or if you have a amplifier, you can hook up the remote power to it, otherwise, leave it off. Then you will have your speaker wires which the fronts are White and White/Black, and Grey and Grey/Black. The rears are Green and Green/Black and Purple and Purple/Black. The ones with the Black striped go with the other matching colors with the black stripe. Then you would just plug in the factory harness to the aftermarket, and aftermarket to the cd player. If you are trying to hard wire into the factory wires, you will have to cut of the harness, find a Haynes or Chilton book at an automotive store and find what wires are what and use the color codes from above to hook back up, factory wires are always different colors. Once again, I strongly advise not to do it this way though. Hope this helps. Good luck.

How to hook up the pioneer stereo to wire harness?

Not real clear on question, but you can buy a direct fit wire harness and the wires are color coded so you don't have to cut and splice your wires on your factory harness.The harness hooks to your factory plug and you wire it to your pioneer stereo wires. Harness is about 7.99 up at most stores.

Hello i would like to add a din head unit a few 6/9s and maybe a sub if poss into my saab 9-3 vector sport 56 plate is it possible with my existing 7 factory fitted speakers so that when i come to sell my...

My suggestion is to go to your local audio shop and pickup a dash kit and wiring harness to hook up the din head unit. I actually wouldn't recommend putting in aftermarket speakers unless you don't plan on reselling or they are blown. You could hook a sub up by running your power wire to your amp like usual, hook your amp turn-on wire to an accessory wire and buy a "line level converter" you will tap into factory speaker wires with this and it will convert it to RCAs. You will only need to do this if you are using the factory head unit. Also, unless the aftermarket unit has features that you want that the factory one doesn't, I wouldn't bother with that either. Good luck. Let me know if you need any more help.
