Deck harness mess

[clean96GST]

Ok so the previous owner pretty much didn't know a whole lot about what he was doing, and he decided to completely butcher the harness. It pretty much sucks driving without music so I really want to get this fixed.

So there are two harnesses merging into one.
This one comes from the back of the car, is this stock?

And then there is this one

And they both come together in a giant mess of splicing, here are the pics.

So what would you guys recommend doing first?

are there 2 harnesses? one female one male? i see pics of the female one which should be the wiring harness adapter for ease on installing new decks. then there should be the stock one that plugs into there so there is no need to splice and cut the original harness.

if thats the case just connect then and it should stasrt to make sense.

some of the wires look like they are still connected to the speakers which should be correct. and only the ones that are not connected to anything are the ones that should connect to the deck which he pulled.

it doesnt look too bad.

There is one male that will fit into the stock deck, one female that the stock deck male will fit into, and a male for the new deck. And I really don't know a thing about car audio, but I've let a few friends who are pretty good with them take a look and they were clueless.

so what i assumed was correct

so what sthe problem. did he take the deck?

if you are installing a new deck? thers already a wiring harness there to make install easy.

No, and he didn't just plug in the adapters like you're thinking. The male to the new deck doesn't just go straight to the female for the old, he spliced a bunch of wires in between and I'm guessing he made some mistakes. If I everything in the deck gets enough power to eject a CD but the screen/anything else won't work.

 

[clean96GST]

Ok so I am still trying to figure this out. Are both of those main harnesses in the pictures stock? if they are couldn't I easily find the color codes and just splice it into the harness for the new deck?

 

[RedTurboEclipse]

the only harness that is stock is the one that continues deep inside the dash.

then you have the harness that i called the female harness that connects to the stock radio harness.. then the wire ends of this is what connects to the aftermarket deck wiring. so then you dont hack the stock harness at all.

Yeah I get the idea of plug and play adapters for the harness, but that isn't how mine is set up, its not like if I unplug the female stock one that goes to the male aftermarket that it will just come free, there are other wires randomly spliced into them, so even if they aren't plugged in they are all connected as one. So what do you think the purple/green harness is for?

 

[RedTurboEclipse]

if thats the case the previous owner did some funky stuff..

those kind of things i would need to be there in person to see.. i suggest consulting someone you know locally to take a look.

Where is the stock ground? I got everything back to just the stock harness, with the male stock deck end, but I cant get the deck to turn on.

The stock factory ground is via the mounting screws into the chassis.

Does it bolt right under where the deck goes? I have one wire bolted on down there but it doesn't go anywhere, and it doesn't look stock. Where does the stock ground usually go?


Edit: I'm also trying to find an adapter that goes from our stock harness female to my new deck male, does anyone know where I could find it?

There isn't a wire stock. Doesn't your radio mount screw into the metal of the center console using 4 sheet metal screws? Those ground the radio. Since your going to use another radio that has a ground wire on it's connector just run it to a easy to access bolt or screw on the console and ground it.

Metra sells the stock mating end for making up the adapter with the connector that came with your new radio. I've seen them at Advanced Auto and picked them up at BB if you talk to the guy that do the installs.

Yeah It wasn't bolted in with those screws when I was trying to get it to work. Would that cause it not to power on? So all I have to do to ground the stock deck is screw it in?

Without a ground the circuit isn't complete and no current will flow.
It would seem like the quickest answer would be to screw it in and see.

Well at the time I wasn't near my car. So I tried bolting it up to the mounting brackets, but it still didn't work. How long do the screws need to be to ground it? Sorry I'm a total stereo newb.

Anyways here is how everything is plugged in now before I bolted it in:

And this is pretty much the only strange looking wiring under the dash, it is a blue wire spliced onto a cut green wire coming out of a harness. Sorry about the dark picture I used my phone.

And the harness that is aftermarket and coming from the back wouldn't be affecting it would it? its not plugged in to anything from the front. This is the one I'm talking about. What do you think this is meant for?

I'm thinking I might just take this to an audio shop and have them take a look at it, because right now I can't figure out why this deck won't turn on. How much do you think they would charge for that?

 

[got_no_sol]

It looks like they bypassed the stock amp. That would be what the "2nd" harness is.

Honestly it doesn't look like a mess to me. The only thing that is potentially bad are the red and black wires running under the radio that I'm guessing are for neons.

Check your radio fuses, and make sure your ground is good. If all else fails, you can tie in to the cigarette lighter ground.

Yeah I'm not even trying to deal with that other harness right now, I'm just trying to get the stock deck to work on the stock harness. He was trying to run ricey neon all over the car so those are probably just left over wires I need to take out.

 

[got_no_sol]

If you're trying to get the stock deck to work, it won't unless you unbypass the amp.

As far as getting it to power on, like I said, check your fuses. Do you own a multimeter? Or even a test light?

O I get it. So what do I need to do to un-bypass it? And yes, I have a multimeter.

 

[got_no_sol]

Depends on how bad of a job they did. If they hacked the factory plug off, it would be a huge pain.

Why not just use an aftermarket hu?

 

[InfiniteGSX]

If your going stock, you need to fully go stock. Stock Stereo requires Stock Amp. Aftermarket Stereo requires Aftermarket Amp, or very expensive harness.

I hate it when people hack the harness off to crimp in the stereo's harness. Yes it could make it look clean for JUST THAT STEREO. Stereo dies, new harness is out... ICK! Just Plug them in the right way people...

Man, I feel your pain. My Talon's harness was hacked 3 times, on the same harness! It was almost only hanging on by one wire. had to pull half the harness out of the dash which wasn't easy, just to repair the wiring.

Not true. I sell the harness at my work for 20$.

Where do you work? I just noticed your from Everett. How much do you think you guys would charge to fix something like this?
