That's really stranger, do you mean even if you do not plug the green connector, the old car radio still have sound comes out? We do really do not understand why,because there is obviously no speakers wire built in, and we didn't see any audio transfer wire on the black connector exepect the small green connector. Is there any other wire connectors you forget to show us? If there is no other wires any more, I can only suggest you to expand the 4 set speaker wires to the car speakers directly, I mean give up the original car amplifier and use the car speakers with the new radio direct.
Regards!

Here are the latest developments.
Whatever I do with the green connector, there is no response from the speakers. However, when I connect the harness with the old radio, but leave the green connector out, the speakers react when I touch the wires with a grounding wire. It looks like the connection with the loudspeakers is only established when the wires are connected to the old radio. Any suggestions? Perhaps I should try to by-pass the trigger function of the old radio by connecting some of its wires with each other.
Or perhaps do all the tests again with the key in the lock in contact position.
Best regards

Thank you for your photo, but that is really stranger that your original car connector do not include speakers wire on the plug, which you can see, there is no wires there which original should be 4 pair wires for speakers from the original car radio wiring diagram.
But you said when you install back the original car radio, and the sound will comes out, so that is my first time met this kind of situation my friend. I think it is the green small inside connector from the picture would do that job, I mean the LD-R, LD-L, EA-R, EA-L, LINE, EA-G. So it means LD-R/LD-L/EA-R/EA-L are positive pin of RCA input, and LINE/EA-G are negative pin of RCA input. Maybe you can try one of the pair with one of the RCA connector from the radio to check, I mean only pick one of them to check if it will have sound, just sa the following link shows which you may need to do wiring modification, please do not worry, you won't loose your warranty!
If this is not work, I only have the suggestion that the first time you mentioned, direct connect the 8 speakers wire to your car speakers, bypass the original car built in amplifier, which may take a lot of wiring and installation job to do. Could you be able to do that?
Best Regards!

Here is the photo you requested.
I just installed my old radio again, with the same wires and there does not seem to be any problem. I only tested if the old radio has a direct connection to the speakers, which it does. Tomorrow I will start some good old trial and error connecting wires.
I will keep you informed.
Best regards

According to your photo, I just wonder where did you get the quadlock connect? Maybe you can give me link if you ordered it from internet seller? And does all other function, such as steering wheel control function are work? Or your car original without steering wheel control function?
And do you mean from the original car radio connector, there is no speakers wire? Cause the photo 4 didn't show the pin out, so I can not define that, would you mind unplug the quadlock and take photo on the front face of original plug? Just as the following photos shows so we can check the pins with/without wire.
I know it's holiday today and you may enjoy the holiday at the moment, so please do not wory and reply me when you are free, ok?
Regards!
Andy

Thanks again for the help.
I attached a couple of photos
Pumpkin 4 shows the wires coming from the car in the green connector and the harness. The connector fits into the harness. The pins in the harness meant for the loudspeakers are not used.
What I thought was an amplifier is the Central Convenience Unit under the passenger seat.
Also attached is a photo with the diagram of the old radio.

And as you also mentioned that your car original with some kind of amplifier built in? Could you mind also take some photos to show where the amplifier are located? I will waitting for you online for another 3 hours, please do not worry!

Does that mean that there would have been appropriate connectors, if only you would have known it was for a Volkswagen? I have an appointment with the car electrician only after new year, so if Pumpkin can send me something that can solve the problem, please do not hesitate.
In the video you kindly made, you show how to bypass the amplifier and that works with my external loudspeaker. But to do that with the car's own loudspeakers, I have to 1) have access to where the wires come together or 2) rewire. The second option should not be necessary, and for the first I had a look at the amplifier, but thought it wiser not to touch.
It would be a great help if you could advice where the loudspeaker wires of a Multivan 2005 come together to allow me to connect the radio directly.
I will send some pictures later today.

I'm sorry for the trouble caused on you, I know understand that you bought an universal 2 DIN device with nornal ISO cable to install on VW car, and that caused the wiring and connector totally different. But I'm glad that you have already sovled it in the electric shop. But if you are not, please contact me back with your information photos, ok? I will try my best to help you solve it.
And as you can see, the item is built in WIFI function with Android system, so I think you can connect the device to internet, and direct download the Tomtom map app to install into the radio. Any other issues, please let me know!

My order number was 204-9664442-9976347
I was told by VW that the wiring was diferent because I bought the car in Germany.
Anyway, I had a look at the amplifier and decided that it was way to tricky to play around with those 200 wires.
I will bring the car to a car electrician to connect the loud speakers correctly, but also do the reverse camera and several other wires.
I have a last question. Where can I find a complete explanation on how to install TomTom on the Pumpkin.
Thanks and best regards

I have a few questions:
1) Should there in all cases be a loudspeaker connection behind the radio, or are there installations with a different wiring diagram?
2) Do I need an amplifier, as one technician suggested, but another denied? If so, what would be recommanded?
3) where can I find the loudspeaker wires to connect directly?
Thanks and best regards
