Unknow Wire

[stlalerodude03]

Hey everybody..im really in a jam...i just baught a new head unit from best buy. i liek to do install on my own. iT was all easy untill i got to this red wire that was in a little bag and i had no idea were it goes. when i called best buy they told me it goes some where in my ign. harness and that they cant tell me anymore because they are not intalling it. theres power to the deck(cd'd ejects) but nothing is displayed on the head unit. PLEASE SOMEONE HELP ME! :wah: Best buy said it will never work inless this wire is hooked up.

[FormulaNERD]

sounds like your constant power is connected (cd will eject, even with the key out) and that red wire goes to a power source that is only "hot" when the key is on... try running it to the sunroof fuse on the passenger side with a temporary wire, and see if that works... if it does you can leave it there, or tap into a wire from the ignition that is "hot" with the key on.

[stlalerodude03]

hey thanks alot ill try that!

[stlalerodude03]

but crap there is one more proble i know where the wire goes on teh car put where does it go on teh head unit/ wireing harness..help again please!

[FormulaNERD]

honestly i couldnt tell you.... the harnesses differ from stereo to stereo

[stlalerodude03]

thanks for all your help

[FormulaNERD]

no prob.... if you post the deck info, maybe someone with that deck can help you.

[Vtolds]

There are no directions or a wiring diagram?

[stlalerodude03]

nothign that mentioned the little red wire..just a basic diagram of how to wire the harness. i read over that thing 10 times and know where does it mention the red wire.

[Vtolds]

Maby it does nothing then.

[b-spot]

Red wire will be called 'ignition' or 'switched power' or 'accesssory power' or something like that

[Molson]

yup, you have to run it to an ignition source 12v. You can use a fuse tap to tap into the fuse block.

[stlalerodude03]

ok so this goes to 12V were does the outher end go...do i splice it with soem wire in the harness?

[Vtolds]

Cant he just splice it into the factory harness turn on wire and have it work?

[b-spot]

The factory "turn on wire" eh? LOL

Easiest is to tap a fuse, like the wipers or something that is on only when the car is.

[stlalerodude03]

what wire do i splice it into tho?

You mean its just a loose wire?

You need to run the power wire from your deck, to a 12V source. This is because our factory harnesses don't actually have an ignition power wire. Don't put it to your harness.

[stlalerodude03]

know inless i fogot to mention this the deck. has power to it but nothign on the display or sound....i have a red loose wire with a connector on the end liek it hooks to a tab our something..this wire goes to a 121v source then this goes to my cd deck...but theres is no hole or connector for this wire on my deck...srry if i keep talking about this topic but i need to know! thanks!

[Vtolds]

What is the deck that you got?

[stlalerodude03]

awia

[Vtolds]

A Awia? that doesnt tell us much need to know a what Awia it is.

[stlalerodude03]

ummm its the cvcx204

[stlalerodude03]

well srry guys i have to goto work but please any info is greatly appreciated.. thanks alot!

[Vtolds]

Well I can tell you that its full description and real name is,

Aiwa 45W x 4 CD Deck with MOSFET Amp/Digital AM/FM Tuner/Detachable Faceplate CDC-X204 Titanium Silver

But I cant find out crap about how to install it.

Good work VT. Way to post that. We really appreciate.

Someone make this guy a mod!

[Vtolds]

I downloaded the owners manual and I found this I hope it helps.

[Molson]

Ok

your deck is going to have 2 power leads, typically a red and a yellow. red being ignition 12v source and yellow being 12v constant. (To keep the clock, radio settings, etc). For our cars, run the yellow through the harness that you bought (like you did, as you say the cd will eject) the red will have to bypass the harness completely and go from the deck to a good 12v IGNITION source, the easiest to find is in the fuse block. (I used drivers side) tap into a fuse that you know is IGN controlled (use a test light).

[sound_xtreme]

99's have a red turn on in the stock harness.

[Vtolds]

I didnt have to run a turn on wire from a ignition switch power, all I did was hook up the harness plug it in, stupid Aiwa headunit.

Oh ya? Ok my post is for at LEAT 2001 and up. Not sure about 2000.

you're not understanding, he knows that one end of the red wire goes to a 12v ignition source, but the other end IS NOT connected to the stereo, and he doesnt know where on the stereo to connect it.

[Molson]

I don't recall reading if he got it new, if so, it should have a wiring diagram.
IIRC the wire came with the harness, not the deck, so he has to clip the red (12v IGN) wire that he probably wired into the harness (which won't do anything) and wire it direct via the loose wire to IGN.

If its too complicated he may want to get someone more experience to do it, or show him, its easier in person.

[Vtolds]

I read the Owners manual for his deck there is no install instructions just useless crap like how to set the clock and tune the radio. THe bestbuy Website say that the Recommend that they install it and in this case it is probably smarter to have them do it.

[FormulaNERD]

i agree with molsons last post. the extra wire is probably included to extend the wire for cars that dont have the ignition power in the harness.

Molson did understand the question. What he means is that the red wire (the red loose wire) will bypass the wire harness all togeather and tie into the HU's Ignition lead. This may be refered to as "switched ac" or "switched 12 volt" on the HU. I may be wrong, but I think that the yellow 12 volt will always be the switched on a aftermarked HU. The red is always a 12 volt constant (which he should have hooked up already). Like Molson said, the newer aleros don't have a 12 volt switched on the wire harness. Or I should say, they do but won't work on a aftermarket HU. The 12 volt switched comes from the "CAM" network that the factory HU comunicates with. If you remove the HU, the CAM will not see the radios bus signal. Without the bus signal, the CAM does not turn on the switched 12 volt. Since panasonic makes most of the delco HU's, some can be wired to turn this on. You would have to sacrifice the cd changer output. and have a delco, panasonic wiring schematic. Sorry about the rambling. The reason that the red wire has a metal hook, is to plug into a fuse bay. Once the red wire is attached to your HU's switched 12 volt, the metal end will plug into a 12 volt fuse bay that is turned on with the ignition. This is any power source that must have the ignition turned over to operate. Example: Your climate control and moon roof are switched. The power seats are not since they operate with the ignition off. I found the moon roof to be the best. The climate control gave a bad feed back into the radio. Kind of like a hiss. I also had to ground the HU seperate from the wire harness. The wire harness ground induced a hiss into the speakers. I just ran a new ground to the frame instead. You will have to buy a fuse from autozone that allows you to plug the new wire into it. It is just a fuse with a slot cut into the top to allow the wire plug.

[FormulaNERD]

no, i was just saying that molson was telling him to connect the wire to 12v switched, but the guy already knew that.... and connecting a loose wire to 12v switched wont do poop unless it's connected to the stereo somehow, and that was the original question that wasnt answered.

[mikegett]

Read his post. He is talking about connecting the loose wire to the HU and then a fuse bank.

[mikegett]

I looked for the fuse that he needed. I thought that it was called a fuse tap but I am getting nothing. Does anyone know what it might be called?

i understand that. the whole point of the post was to find WHERE ON THE HU he should connect the wire to. you can tell someone to connect a wire to the HU, but that doesnt exactly help at all.

[mikegett]

Molson stated the colors of the HU wires. He then stated the yellow HU wire went through the harness. Then the red bypassed the harness to the 12volt ignition. He was referencing the red HU wire he had just described. Not the red loose wire. Either way, it doesn't matter as long as the 12 volt switched wire (from the HU) is what the loose wire attaches to. I had stated that I thought that molson was mistaken and the yellow was the switched ACC. I just checked my manual and he was correct.
" 1 ACC Red Connect where the power comes on
when the ignition is in the ACC
position.
2 B+ Yellow Connect where the power is constantly
available, regardless of the ignition
switch's position."
So as Molson stated, the red HU wire will bypass the harness and connect to the loose red wire to plug into the fuse bay.
This is off subject, but I was wandering if FormulaNerd ever recieved a refund from 99blackalero. It kind of shocked me. I always thought he seemed like a nice guy in the forums.

[mike2002]

maybe i read it wrong, but what it sounded like is the red wire got pulled out of the plug, that plugs into the deck if so, all he has to do is push it back in the right spot, but you should call aiwa for the location of the redwire.

i might have read it wrong though

[stlalerodude03]

thanks for all of your help guys i really apprectiate it ill try it out tommorow and post if it works or not because its gettign reall frusterating....why dotn they just ass this wire to the harness and make alot of things eaisier, thanks for everything

[stlalerodude03]

it works great now and loosk asweome thansk for all the help if you wann see just check out my car domain site...tyhanks again

[BartTN]

I am at a lost. I have read about all the wires here also. I find myself looking for a switched 12+. I have moved my HU to the trunk and am in the middle of installing a computer with touch screen. Everything is ready but can not locate a ACC power anywhere. The closet I got was the AC controls. I tried the fuse block on both the drivers and passenger side and they all show hot, doesn't matter ign on or not. Any ideals???

Thanks Bart

[mikegett]

I am not sure of what you may be testing. If everything is hot, I would assume your on the wrong side of the fuse box. On the drivers side fuse box, just find something like your AC control or moonroof (what I used). From there, You need a fuse tap that plugs into the moonroof fuse slot. It will have a slot for keeping your old moonroof fuse and a slot to add a new one. Just plug tap into it with a wire and run it to your trunk. The only thing I am confused about is the HU. If you are moving the original HU to the rear, there will still be a 12 volt switched. The problem comes from adding a aftermarket HU. The factory HU gets its switched 12volt from a bus signal on the cars network. If you remove the HU, the network doesn't get a return signal to turn it on.

theres your problem.. jk.. Try this shiz out mofo, i'm not sure if this will help., but this is a diagram. (http://www.installdr.com/Harnesses/GM-Wiring.pdf)

[BartTN]

mikegett,

I tested both driver and passenger side fuse panels (where the fuses are in the slots) and used a multimeter and the fuses were showing 12 volts on all. I must admit I am at a loss.


EDIT: Ok color me stupid... When you test the HU you have to have the plug in the stereo for it to see it and send power when the acc is on. I had the plug pulled and was checking that way. Thanks again!!!
