(newbie) Installing a car stereo
We've gotten hold of a car stereo to replace the worn out one that was
in the car, but since I've never installed a car stereo I don't really know where to start. The problem is that the old stereo had an external (non-standard) connector, while the wires went directly into the stereo. But without any manual I'm unable to find out which wires correspond to what. With the new stereo there's a standard connector (which I've gotten hold of), and on top of it is the connector's pinouts, so all I need to know now is what wire *from the car* corresponds to the speakers, car battery etc. What do I do, which wires am I looking for and where do I start? (I have a multimeter in case that helps). |

Well, knowing what kind of car it is MAY allow us to tell you what wires are which based on color codes Looks of good advice here from you and Brian. Thanks! I'm going to print it out and see what I can find out. I'm also trying to contact the producer of the old stereo that has been used up to now (Fujitsu Ten CE-4850EX 1) as that would help immensly (there wires go straight into the unit; there's no connector on the back of it as with the newer Denon I'm replacing it with). But getting back to your and Brian's question: the car is a Hyundai Pony. I can't remember from which year, but I can check if it makes a difference. |

I had some of those and it's safe to say that it an 84-87. They don't make
sports cars like that anymore. I highly doubt that you'll even find a harness for it or any info on the car outside of Canada.

I've had a closer look at the old Fujitsu Ten head unit (the one that I'm throwing out), and it is labelled and has a couple of smaller connectors coming out of it, but in addition, one or two additional connectors (for the car) have been attached. Looks like a mess, but with my multimeter I should be able to figure it out... I think ;-) I'll get back to you guys once I've given it a go. |

I Canada the Hyundai Pony that looked like this

Either way, the stock speakers will probably sound terrible with the new deck - you may want to simply replace them with some new, cheap speakers, which will come with their own wires as well. Luck has it that the seller of the Denon car stereo (DCR-470R) also included a set of speakers which he said sounded pretty nice, so I'll see if I can try that out once I've connected the stereo. I had a look at the old stereo (Fujitsu Ten CE-4850EX I) and did find a connection diagram, so I'm in luck! So from now on it'll just be a matter of tracing the wires back to the connection block, then replacing it with the new connectors that will go to the new Denon stereo. The old Fujitsu Ten car stereo does indeed have a + and - output going to each speaker, but I haven't had a chance to check out the actual speakers in the car to see if they're commonly grounded or not. Hopefully it won't be too much work to attach new wires if they are. The old stereo has the following connection pins: - Power supply - Auto ant. - Back up - Speaker left + - Speaker left - - Speaker right + - Speaker right - As for - I can see that's connected directly to the chassis of the unit. "Power supply" means +12V to the battery, right? So what's "auto ant." (powered raising/lowering of the antenna?) and "back up" for? Now, the new Denon car stereo which I'm going to install. It has two big connectors (side by side) on the back of the unit, and the pinout shown on top of the unit tells me the following pinout signals: - GND - ACC - Battery - Remote/P. ant. - Front speaker left + - Front speaker left - - Front speaker right + - Front speaker right - - Rear speaker left + - Rear speaker left - - Rear speaker right + - Rear speaker right - So how do I adapt the connection for the old stereo to the new one? 1) I only have one set of speakers. Does it matter if I use the rear or front set of outputs? 2) Obviously GND is the same as the chassis connection of the old stereo (-12V), right? 3) What does ACC correspond to on the old stereo? 4) I assume "Battery" is the same as +12V? 5) "Remote/p.ant" -again, I assume this is for cars with motorized antennas (raising and lowering), which my ageing car doesn't. But what does the shared "remote" function do? Does it have something to do with the CD-changer option? |

You'll want to put back speakers in. It will make quite a difference. Heheh, there may not be anywhere to PUT back speakers in that car - ACC accessory, probably for remote amps. Nope... power from the ACCESSORY position on the car's ignition switch. - Remote/P. ant. or maybe this is for the remote amp *and* the power antenae? These are usually interchangeable... all it does is provide an output 12V signal from the deck to trigger whatever external device you want. The only time they're really "different" functions is with the few decks that power off and retract the antenna when the deck isn't actually on the radio feature. So how do I adapt the connection for the old stereo to the new one? I'm not sure what you mean. Fine the wire that turns on and off with the ignition and use this for (I think) the yellow wire on the denon. The red wire iirc should be the one for illumination. The Denon deck doesn't have an illumination wire, according to what the OP posted. The "standard" wire colors a Yellow - constant +12V Red - switched (ACC) +12V Blue or blue/white - remote turn-on output Black - ground In my experience, if there is an illumination/dimmer wire, it's usually orange. The Denon may not match these color codes, but the OP listed the pinout as printed on the deck's label anyway. |

Heheh, there may not be anywhere to PUT back speakers in that car Too true ;-) But since I received new speakers along with the stereo I could replace the existing ones. Anyone know how to get access to the speakers in that car? I see now screws. Needless to say I don't have much experience with cars ;-) The Denon deck doesn't have an illumination wire, according to what the OP posted. The "standard" wire colors a Yellow - constant +12V Red - switched (ACC) +12V Blue or blue/white - remote turn-on output Black - ground These are the wire colors on the 3rd party plug which fits the Denon. What happens if I exchange the constant and switched +12V wires? Will I fry something? |

Nope, but like brian said, the deck may not turn on and off with the key... and you'll likely lose any radio stations you program when the key is turned off. The first stereo I ever put in (when dinosaurs roamed the earth, lol) I did exactly this. I didn't have a multimeter and I hacked the wiring harness. I ended up finding the always on wire so I twisted the two power wires together an attached it to this one (twisted with electrical tape of course). It never lost the radio stations and I could turn on the radio with the key in the ignition. It didn't hurt anything. I did always have to turn off the radio after taking the key out though. :-) brian |

It works! It works!!
At first it didn't, then I realized that there's supposed to be a 10A fuse right next to the power/audio connectors on the Denon. I didn't have any fuses, so I (oops!! I know I shouldn't..) connected a small wire to short it, just so I could test it, and it powered up and worked fine! Thanks guys! I'm going to get hold of that fuse, then move on to see about those speakers -if I can remove the ones that are there and replace them with the newer, better ones, then finally look into that special CD-changer connector to see if I can connect the ipod directly to it. |

If you can get ahold of the plug off the actually CD changer, or a dead changer that you can cut the plug from, you MAY find that the wires in that cable are color-coded already and it'll be easy to splice in a 3.5mm stereo plug to plug into your iPod's headphone jack. At first glance it looks like an S-video connector, but I haven't really checked properly. If it's a proprietary plug I might have to do what you suggest. I've already contacted a Denon dealer and awaiting a reply, so we'll see how that goes. I'll get back here if I manage to get it to work -perhaps others might be interested in doing the same. |

Yeah, I read that as well, but having just had a look at my own Denon it certainly isn't a 13 pin connector. I count 8 pins. Here's a couple of photos I've taken: http://www.esnips.com/web/no-spam2-files It *could* be a mini-DIN as you're suggesting. I'll have to look around to verify this. I've already contacted a Denon dealer and awaiting a reply, so we'll see how that goes. That's probably your best bet... you could also check their website for technical-support info, as those would be the people most likely to actually have the info you need. Tried that, but there's just about nothing available regarding car audio. The only thing that I thought could help was the Japanese site's user-manual download page (http://denon.jp/ownersmanual/index.html) I didn't find my DCR-470R there, but tried looking through some other car audio manuals. Doesn't look like they want to give that information away, at least not in their manuals. I'm still awaiting a reply from a Denon dealer. |

Okay, that's definitely a mini-DIN; that matches the right-most picture in the Wikipedia link. Obviously the changer BigBob linked to is not one that's compatible with your deck. Given that, I'd say there's a pretty good chance it has separate pins for analog audio - there are more than enough there for audio and control signals. |

If he's lucky, all he has to do is tie one of the wires to +12v or ground and the head unit should think there's a changer there. If he's unlucky, there will be some sort of binary conversation going on between the deck and the changer. Normally, the changer doesn't just start playing though. You may have to send it a command to get the audio channel to open. On the other hand, it may always be open. If you had a changer to hack, this would be a lot easier. brian |

Yeah, hacking an external input would be great as I just tried the head out with that cassette adapter of mine. It worked just fine, but.... the tape deck makes an awful lot of noise in one of the directions (it has to be the direction the cassette adapter plays!! It only plays in one direction). I tried playing an ordinary audio cassette as well and yes, the tape deck makes relatively loud and annoying mechanical noise when one side of the tape is played while the other side is fine. I guess it's just the way the Denon deck is designed or something. An external audio input would do away with all that mechanic stuff. |
