I bought the Double DIN unit off of "JDM" on this forum. I too will tackle this beast along with some audio guys I met... and yes, I'll keep you all posted. By the way, I've ordered a Pioneer FH-p9200 to fit that space, so A/C working or not... that B*tch is going in!!!

OH man, someone figure this out pleeeeeze. I'm no good with this kind of stuff but I'm dying to replace that factory unit.

I found the following in this thread:

"it also appears that you can swap the A/C systems control unit (single zone & dual zone) if you set the ECM for it....still reading"

 

The general consensus on the thread is that this posting is a load of crap... but on the chance that there's an ounce of truth to it, it might bear looking into...

Next step... installation.

So, what are you going to do with the hvac/stereo? I like the concept, just trying to figure out how you are going to do everything, with what you have, and what you will/will not retain. Any info. is all good.

Hey sorry my install is delayed as i figured out friday that my a/c is broke.. :(

 

so im taking it in and as soon as i get back i will try again :)

 

i just wish i could find out for sure which wires shoudl be 12v

gfxdave99,

We're all behind you on this one... I'm getting to the point were I'll sacrifice the friggin' A/C all together just to put the Double DIN unit I have in! But it's getting cold in the Northwest and that's a risk I can't take. Can you post what you've figured out with the A/C wiring so far?

I was going to start messing around with my voltmeter/continuity tester to see if i can narrow down what needs power put alas my 9v battery in my meter was dead (sigh)

 

So I will get a new battery and start playing around with the jdm unit tomorrow or i guess tonight (monday) once i get that im gonna put 12v to it and see if it lights up on juice alone and then figure out a way to rig 12v connections into the wire

If you want some help with this, plesae let me know, I would be very interested in getting this to work.

not sure if i read through it all but isnt thare a way to just tag the power and speaker connects and somehow tuck the normal radio and climate contol stuff away thats what i have had to do with some chevy's with an onstar system, just gotta test to see what is what on the plugs for everything, also what about the antenna too, maybe its a crazy idea and maybe somebody already suggested it and i didnt see it but it just might work.

That is the data sheet for the Oki Semi display controller. Look at the pin out on the package, and find the Vdisp and Vcc pins on the package. According to datasheet, the Vcc is 5V and Vdisp is 8-16V (which I really think its just 12V). From there, you can do a continuity check to see where that Vdisp pin is also connected to. I would guess that it will be connected to the ACC power coming in from the plug. The Vcc for the chip is probably powered from a voltage regulator on the controller board itself, converting the 5V from the 12V supply.

 

Also, find the gnd pin on that package, and then ohm it out to the connector and see which pins it is connected to. With those 2 pins out of the way, you are at least 1/4 of the battle done I hope.

 

I don't know what else is on your JDM board, since I haven't seen it, and I can't tell which is what from the photos that you have. If there is other active IC on that board, it would be easy to get a datasheet for those IC and get the pinout, and figure out where it is connected to. May be that will tell you where the rest of the pins will go. If you are in CA I would love to take a look, I am always in the lab anyways.

Upon further reading, I realize that the auto-ac control module is actually separate and sitting under the glove box. I think the front panel control is just a GUI interface. Looking at the i88 connector, there is only 4 signals described by the schematics. Power, Gnd, and a pair of signals travelling together. If I have to guess, the pair of signal would be a 2-wire communication interface. Example of 2-wire interface would be RS232(serial port), USB, SATA, CAN bus. I would guess at this point to be a CAN bus. I think all the front panel does is to convert the user input into data packets and send them to the control unit, and the control unit does all the coordination work.

 

If that's the case, the JDM circuit board should contain nothing more than the display driver IC and a serial comm IC, along with some passives and voltage regulator. If you can find the serial comm IC and ohm it out to the connector, you should be able to nail your remaining 2 wires to the AC control unit. If you are unsure of the polarity, check the US unit for the same comm IC for the polarity on the mating plug. Can't mix tx/rx there.

 

Although at this point its purely my guess, I can confirm it if you have more detail pictures of the JDM unit. If my guess is correct though, it makes me wonder whether the actual JDM auto-ac control unit (not the face plate front panel you got) is same as the US unit. For CAN bus, all they had to do is to remap some address range for a particular function and it would render their unit useless in another market. In any case, first thing to do is still to find power and ground to the connector. At least your front panel should power up with some dummy default display.

From earlier "http://legacygt.com/forums/skynetim/statusicon/post_old.gifhttp://legacygt.com/forums/skynetim/misc/sendpm.gif http://legacygt.com/forums/skynetim/misc/find.gif http://legacygt.com/forums/skynetim/buttons/edit.gif http://legacygt.com/forums/skynetim/buttons/quote.gif http://legacygt.com/forums/skynetim/buttons/qreply.gif My diagram shows i88 connector as 8 pins; pin1 (GOr-green/orange) is +12V in, Pin5(BY-black/yellow) goes to ground; pin7(W-white) goes to B15 on "auto ac control module" at B283 connector; pin 3 (WB-white/black) goes to B16 on B283 connector. Check these colors for your connector, maybe check 1 is +12v and 5 is ground on the plug when its out of socket....

I've just completed my AVO double din conversion. About 1 hr to fit. used dimil's walk through (cabin air filter) and the information from jp928's setup (cd changer socket on 05 hu). I've installed an AlpineCDA-9847 with I-pod adapter. The spare din has been filled with a subaru wrx cubby above the head unit. Lost one screw (had spares) and relatively easy to fit. Shame the folk in the US have LHD and dual climate.

Costs avo 2din panel $340.00 around £170.00 ish

wrx cubby £17.00 (bought from local dealer)

Total £187.00

The head unit I already had from my old Forester along with the iso converter. The sound is 100 times better than the old one and everything works.
