Question about Pioneer DEH-225 CD Changer

1 Answer

Wiring Pioneer DEH-225 to 1996 Kia Sportage

Okay, so I have NEVER wired a car stereo of any kind, but I am pretty good at mechanicals and pulling apart/slapping things together again.

My friend gave me her old DEH-225. It has the 12 pins, so I am good with that but the generic wiring color codes don't quite sink up with this Pioneer. To start with, there are no violet (purple) wires. There is a green/red and what may be gray (or white) and red. It's impossible for me to tell the white & white/black wires from the grey & grey/black wires. Just too dirty, I suppose. I suppose I could do trial and error, but I am a little worried about whether mixing them up would be a detrimental escapade. Is there a way to tell what's what just by looking at where they fall in order of the 12 pins??

I found the 1996 Kia Sportage Car Stereo Radio Wiring Diagram. My only question with that is... I've got the option of the Constant 12v and the Switched 12v... So, my best guess is to hook up the battery wire from the Pioneer to the Switched so as not to run down the battery???

Help much appreciated! ;^)

    Okay... I found a picture that may have led me to the answer.

    I matched the wiring on my 12 pin to the wiring on a picture of a 12 pin being sold on Ebay that is 'supposed' to be compatible with the DEH-225. I ran a grid from left to right with the pins matching directions and then matched the color codes to the Kia wiring diagram. Here's what I got... Does it make sense?

    Can I just wrap these up with electrical tape and be done/safe? Or do I need to go buy the same pink end cap things that are leftover on the ends from the previous install?

    So, no power. ERGH. Everything is correct but there's an extra wire floating around (a second grounding wire?). It slipped onto a metal prong that jutted out from the back of the stock stereo. The thing is, all 12 wires are perfect. Now, the stock stereo had stopped getting power... Any ideas if it's something else that is plaguing both of them? (Not that the stock stereo is worth keeping...)

The difference between constant and switched 12V is the constant is usually for the clock and memory. it draws precious little current. the switched would be for the radio and amp once the car is turned on. You can use tape but either a wire nut (not the pink ones) or a crimp on cap would be better than using tape.

    Is the wire floating around from the car side or from the stereo side? I doubt that it's a separate ground unless it's from the speaker side of the wiring. More than likely, you've blown a fuse but rarely do factory stereos have protection fuses so you may have done internal damage.

How do you install a car stereo into a Kia spectra


Well depends on what year it is? You can go to a car audio store or even walmart and buy an in dash stereo kit for like $15 and a wiring harness for like another $5-$10 If you have the wiring harness its pretty much just a matter of plugging that into the dash and there you go.

My same model did this too. The wiring harness may have gone bad. Try direct wiring the stereo or replacing the wiring harness if you can get one. This fixed the problem for me.

Hi,

Pioneer follows standard color coding for stereo/headunit wiring. Pioneer car stereos needs two wires plus the ground wire to be activated. The yellow is connected to the always on B+12 such as the positive terminal of the battery, the red goes to a switched B+12 such as the ACC of the IGN switch while the black of course goes to the chassis/body ground.

Should the above been done correctly and problem persist, then perhaps the fuse may have blown, there is a loose connector at the rear of the head unit or a probable internal electronic defect has developed.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
