yes, correct.

 

What's the deal with ac? How do you get it to start working?

 

thats the million dollar question! we are all looking for this answer!

 

So to clarify no one has ac working then that did this conversion as of yet?

 

not noone. but everybody has to find own way. each one have to invent special device to adopt new ac unit to old car. but pcm3 itself working. this is all about beauty, no more.

 

The 997.2 controls the ac compressor direct over a relay from the user ac control panel. The 997.1 controls the ac compressor from the MCU over a software command, complete different wiring. So there is no plug and play.
i tooked a look at both wiring diagram, it is doable but you will have maybe to cut wires and add some electronic and and...

Less efford and the only working solution would be, buy a 2009 997.1 turbo ac control unit from ebay or teile.com. There will be one problem left, the heating sensor is also differnt, serge explaint already. But that would be easy to fix.

After all this swaps, you will maybe find out, the PCM 3 is also dated. A dension will work and will do a BT streaming for spotify.
If have both PCM,s for me the look is the only big differnt.

Also don't forget the change the FM antenna amplifer control box. The PCM 3 uses a single wire antenna diversty.

 

 

Yea I mean if this was any better documented or easier and given the hassle with the AC I guess I van see people doing it as pcm3 is nicer than 2 but its not. Its a major undertaking and I read all 29 pages in here. If I go with say Pioneer 8100nex and oem looking rear backup camera and sirius integration and black out trim I think you're getting a lot more value and way more functionality and minimal hassle compared to this? I'd give up the nav and song info in the gauge cluster as I never use them anyway, always look at the screen. Is that all that's lost? I don't have a multifunction steering wheel either.

 

alot of members here already done this swap and enjoy their pcm3. to do or not - anyway its each own choice. who love dension and pioneer - this all in separate topics please, dont mix everything.

 

56 dension and nexus 5 and spotify BT streaming work in m case.
changing the speaker set in the doors will be a much nicer improvment...

If have a PCM 3 in my spyder and a PCM 2.1 in my turbo. I completly understand the PCM 2.1 looks ultra dated like a tube driven unit.

Pls do not blame me

 

First of all many thanks to Tim and Serg for their help.

At the moment iam at the amp.

At my old amp i have the following Pins

a5 front left dashboard + - at the new amp it should be a12
a15 - a2
a7rear left + - a6
a17 rear left - - a16
a9 speaker front + - a5
a19 speaker front - - a15
a11 swichted plus - b6 small black pl
a1 terminal 30 - a1
a2 terminal 30 - a11
a13 center speaker + - a4
a3 center speaker - - a14
a10 speaker front right + - a10
a20 speaker front right - - a20
a6 rear right + - a17
a16 rear right - - a7
a4front right dashboard + - a13
a14 fron right dashboard - - a3

This should be right or?

But what is with the other pins from the black plug:

b2 in fronth right +
b8 in fronth right -
b1front left +
b7 front left -
b4 rear right +
b10 rear right -
b3 rear left +
b9 rear left -

At the PCM 2.1 i change the brown plug as serg said:

I have there at pcm2.1 at pcm 3 it should go to:

b6 speaker front - left b7
b5 speaker front + left b3
b8 speaker rear left - b8
b7 speaker rear left + b4
b2 speaker rear right- b5
b1 speaker rear right + b1
b4 speaker front right - b6
b3 speaker front right+ b2

Can anybody help me if thats right and where can i get ring terminators for the most bus or what do i need to plug the 2 most fibre cables to the adapter?

You need a wiring diagram with all the details. I've done this and even with it all to hand it was hard to complete. I was given it by one of the guys from this thread. I'll see if I can find the ones he made up.

 

I checked the wiring diagrams in piwis and with help of this i wrote out the differences.

In my oppionion it should work when i pin it like i wrote it there or do i have a missunderstanding?

 

as I know he have all that diagrams.
