ISO: harness pinout for 2008 Ltd. Radio/HVAC

Yup, the vendor's even paying to have it picked up from my house. Nice folks! The photo didn't hurt. Hooray for macro.

 

I've gotta wonder how many PM's Opie gets that start with "you don't know me but..." I felt really bad bugging him in the first place. I just don't feel like I/we should write this up until we're sure that people's HVAC systems won't melt down after swapping :)

Ha ha. Once I get to pull the '08 radio out again and get the model/serial number, proving that it's an '08 radio, I think I'll be happy with it not going to melt down anyone's stuff. However you can always put a disclaimer on the write up saying that each person does this at his/her own risk. :)

 

Anyway, glad this little mystery (at least to me) has been worked on and I look forward to seeing when you get yours in. Keep us posted. :)

On at least 2 occasions, a -67B 2008 LGT radio (P204UH) has worked in 2005 LGT's.

 

Hmm, maybe there's some confusion arising from refering to radios by

car model-year instead of faceplate model ID. Because I just ordered

what I thought to be a MY07 radio and installed it in my 2006, using the

Subaru part number identified in the massive "2007 SpecB" thread:

But this HU, which works quite nicely in my 2006 car, is a P204-UH.

 

I suggest we just refer to these radios by faceplate model ID from

now on ...

Very interesting thread...IIRC when looking into this before there was some difference in the wiring for the A/C and heat controls indicated on the wiring diagrams. I wonder if those were just design differences that function the same way.

 

When you have the '08 system in the '05 does everything actually "work"? I see you said the LED indicated that the different functions where selected, but did the A/C actually come on, defrost, heat, fan, etc.

 

I am very, very interested in this because if this is true...then the JDM Dual Climate Control bezels should also work which would allow the use of an aftermarket radio.

The blower worked, and I know the A/C worked and was blowing cold air, but I actually didn't try the heat (sorry, was silly of me). But this weekend is extremely light for me at work, so I'll swap 'em again, and check though.

 

Didn't someone try the JDM Dual Climate bezel with no luck? :confused:

That would be awesome if you could check that.

 

I don't think anyone ever tried the dual climate control bezel...I think they tried one of the single climate control bezels.

If I can get out of work early enough today (it's been a crazy day so far), I'll do it this evening. If not, it'll be tomorrow morning.

I swapped 'em both again tonight. Everything works fine. Heat/AC, hazzards, CD, FM, AM, SOS-WoW thing. illumination, dimming, etc.

 

Uploading pics/vids now. Might take a while, I have to email them to myself off my phone, and the vids are big files.

So where can you order the JDM dual zone bezel from? I checked japan parts today, and couldn't find it. Depending on the cost, I might pick one up and give it a shot.

After doing a lot of re-research this morning (research I had done years ago but forgetting information), I read like 3 full threads on here this morning.

 

http://legacygt.com/forums/showthread.php?t=46539

 

http://www.legacygt.com/forums/showthread.php?t=82924&highlight=dual+din

 

And it looks like they have tried the dual zone dual din kit from japanparts and were unsuccessful. I am in no way, shape, or form an electrical engineer, so I doubt I'll be picking up one from japanparts.

 

And it's funny, a thought just popped into my head, if the 08's work in the 05's, the 05's probably work in the 08's.....and I shouldn't have sold the highline dual din kit I had in the 05. :lol:

I'm gonna try and contact Kenwood to see if I can get wiring schematics for this. I'd like to know what the 8 pins are on there. There was talk in one of the other threads I linked to the other day that said that the OEM HVAC plugs don't carry power through them. So I'm interested to see how the Dual Din JDM piece gets power.

Glad to see you're looking into the JDM ACC controller unit. Not to discourage you (really!), but did you see this thread from 2005 by gfxdave99: Newsflash : I Ordered it.... He eventually gave up and mailed the unit to daswrx (who, a few months prior, had posted this thread showing his labor-intensive "split-the-display-board" install).

 

Several weeks later, gfxdave99 passed along an update from daswrx in post #150. There was talk about daswrx possibly testing a second unit from S0CalGT to make sure the first one wasn't blown, but nothing further was mentioned in that thread.

 

BTW, interesting point made in that thread in this reply by "ur a bus":

<snip>1. Why do you think the climate control is dependent of the HU?<snip>

I have looked enough at Vacation Pictures to know that some of the buttons on the head unit are used for diagnostic functions of the climate control system. Other than that I don't know.

 

If you separate the two units, you lose the self-diagnostic function of the ACC system.

I have a more fundamental question:

 

In the schematics and wiring diagrams I've seen, the 8-pin plug that has the subwoofer output and "OnStar" phone input (on 2005/2006) or Aux input (2007 and up) has a single pin for the ACC control. In Deerkiller's 2007 Spec B Radio information thread, that is a Green wire at pin #8 in his 2005.

 

The second 8-pin socket, which has pins for incoming Nav audio (among other things), has two pins for the ACC control.

 

I don't own a Legacy, and it's been awhile since I looked at this, but it seems like I've only seen people showing their US cars having just one 8-pin plug, which plugged into the socket with the subwoofer or Aux-in wires (with the single wire for ACC control). The cars had no connector plugged into the other 8-pin socket.

 

That would be a significant difference — single vs. 2-wire connection for ACC control.

 

The schematics for the CQ-EF1561L and CQ-EF1560L radios show the two data bus wires, plus "Ig" (+12V Ignition, no doubt) on the second 8-pin connector going essentially straight into the main microcontroller (through some buffering circuits).

 

So is this a USDM vs. JDM issue? Or do any USDM models use the second plug (with the 2-wires for ACC)?

 

It would be helpful to ask daswrx exactly how he connected the JDM controller to get it working as much as it did (except he hasn't signed on here since early November).

 

ADDED: The single wire is not for A/C control. See my reply, below.

Thanks for the insight SVX. I had seen the Newsflash thread, and signed it off as a single-zone vs. a dual zone issue. But you bring up some interesting points. I'll have to go over them in the AM as the beer has flowed like wine tonight. lol. Thanks for the posts. :)

I took a little "vacation," and determined that pin #8 on the first connector is actually for Illumination Control ("Bright" mode or dimmer cancellation function). That solved a little mystery of how the radio display brightness was changed when you push the Bright button on the clock.

 

This leads me to believe that all Legacies with the integrated A/C controls have the second 8-pin harness/plug, but a bunch of people didn't mention it or show it in their pictures.

When i had sent my single din unit out basically he got it to light up and thats about it. Its currently sitting in a box in my garage and can be yours for the cost of shipping if you want it :)

My P203-UH certainly has the second 8-pin plug (and I moved it over

when I installed my P204-UH, for MP3 and aux-in capability).

I'd love to see what I could do with it. What do you think shipping would run? PM me if needed.

I posted a reply regarding the need for some of the radio (audio) buttons for diagnostic mode in the "hack up the radio" thread, here.

If zmarko doesn't have any luck, I'd like to take a look (although I don't have a Legacy at the moment, so that will limit how much testing I could do). At the very least, I'd determine the pin-out of the 8-pin connector, take a closer look at the ICs on the boards, and figure out how to get it into self-diagnostic mode.

This thing is probably light enough (less than 13oz) to go via First Class (around $2 to $3), but if you pay online and print your own label, Priority Mail is only $4.80, with free Delivery Confirmation.
