Unknown connector behind stock head

Okay, so I get my new MkII and buy some cheap head unit from Best Buy as well as the harness that should go along with it. I get to my buddies house and we begin to disassemble the interior and take out the stock head unit.

First off I do not have premium sound, the stock unit was only a casette and radio. I don't have a picture of what I found yet, but I will by the end of the day. It was 8 pins on top, and 6 on the bottom, seperated by a 2 pin wide spacer:

|oooooooo|
|ooo--ooo|

There's some electrical tape on the wires behind the connector so I am thinking maybe this guy butchered the wiring himself maybe, so if any of you know anything about this connector let me know- Hell I may even be so inclined as to buy the head unit this connector is for just to avoid any BS with installing it.

The guy as Best Buy said I would have to rewire the entire car, speaker-to-speaker. That is NOT something I know how to do, or want to pay for just to listen to a damn CD. Anyways, any input would be muuuuch appreciated so thanks in advance.

follow the wiring loom, it should go to a small external amp under the dash which has the connectors you need, at least thats what my setup had. i ran into the same problem as you did, pulled the dash and went what the f is this?

Hmm,thanks, i'll check that when I get home- Can I ask if the thing you found went directly into your head unit, or what? Either way, if this doesn't work I'll post some pics, hopefully it isn't some proprietary connector...

yes it went directly into my head unit, same connector you are describing, went to an amp just behind where the head unit was situated. i would send pics but i have since put the head unit and amp in my corolla.

From what I can tell it looks like some definate butchering- But what would be compatable with that I don't, I'd really like to avoid having to go through all of those wires manually, but if need be...

That looks a lot like the stock 14 pin premium connector, oddly enough. I can't imagine why someone would splice in one of those, though. The only route I can think of is they bought the car without the premium sound, later wanted to upgrade to the stock premium unit, and spliced in a stock connector...but I'm not even sure that would work. Maybe it didn't, and they gave up and got rid of the stock premium unit, but left in the hack job. Did the radio work at all when you bought the car?

Simplest route forward from here would be to remove the 14 pin connector and splice in an aftermarket-compatible connector at the same point. Hopefully nothing else is butchered.

Hey can someone post a pic of the Premium head unit? If that is the case then I can get my $110 back from Best Buy and use it to buy (hopefully) a double DIN premium CD player.

EDIT

The back of the unit I mean, with the connector.

Someone may have spliced that in because the previous one was cut with the stereo it was attached to during a theft.

Or the entire car could have been stolen and the thief ripped the stereo out and left it on the ground just to be ironic.

Yeah, that's definitely a premium stereo connector, and you'll be having difficulties trying to wire a new headunit in. What are your intentions now? Stay with a stock premium HU or still go aftermarket? Do you need any guidance as to what needs to be done to go aftermarket?

Well I'm not staying with the HU that was in there when I got it, no way. What was in there was nothing more than a radio/casette player and I'd really like to be able to play CDs, I know that's a fancy new thing nowadays but...

No, but seriously if my HU could play mp3s I'd really love that, RW compatable would be great too, but now that we know its a premium connector to they make a harness for that? I can tell you I already have an aftermarket HU thats simple, looks great with the interior and does everything I need so if I could get a harness for that I would love you or whoever got me hooked up with one...

Well, the bad news is that there's only one (that I know of) connector that will connect to the stock connector. The problem is that's it ~$50 and only availabe in European online stores. First off, are you sure you don't have the premium sound system? Just because you have a radio and cassette doesn't mean you don't. I had that too, and I assure you I did have the premium system.

I also don't have subs, or an amp under the seat... Any other way to tell?

The lack of a sub is somewhat indicative, but check to see if you have any amps behind the driver's side rear plastic panel. It's the one where the seatbelt goes into.

Nope, the seatbelt was busted so I have been in there quite a bit, nothing even resembling an amp... And what did you say about that harness? Why would it be $50+?

The harness is expensive since it's not availble in the US and you'll have to pay for exchange rates and international shipping. For whatever reason, you have a non-premium stereo with a premium stereo connector. The only way to get something aftermarket in is to do some custom wiring, although not as far as "rewire the entire car, speaker-to-speaker."

Alright, that shouldn't be so bad then, I'll do some searching for wiring diagrams, but all the one's I've seen so far are a bit on the "WTF?" side. I should be able to get this though.

If it's already been hacked up, why are you trying to save that connector for use with a different stereo? Just cut it out and splice in the stock internally amplified harness, and go from there. That's a little more work, but getting connectors to work with it, will be alot easier and cheaper. Or the other option is if you're going with an aftermarket stereo, just wire it's harness directly into the existing wires and forget about it. If you don't have any stock amps that harness makes no sense anyway.
