Hi I'm trying to find the full pin out for a ASK Sound Amplifier Basic 4F0910223G Amplifier as I'm having to replace the wiring for an 2006 Audi A6, since the car has gone through a rebuild and modification and has had every electrical component moved by someone else, I've not seen which wires are meant to go where, there is also a twin cable plug I need to wire in as well as the main one any idea what it does and where I need to connect it to.

If anyone can help I greatly appreciate it.

4F0 910 223 G? You mean 4F0 035 223 G? https://parts.audiusa.com/p/48794996/4F0035223G.html This is the Bose 6000 amp. Don't know what ASK means.

If you go to cardiagn.com, look for Audi A6 4F manuals, look for the Communications one. In it:

As for the physical routing of wires in the car, there's no record of that. The Comms manual gives you the pin out, the wiring diagrams document will show the ends points of the wires, but nothing shows laying wires around the chassis. The wiring diagrams document at the end should show where all the electrical components are normally located. But cardiagn.com is a pita to use for extensive lookup. You'd be better off finding PDF copies of the documents you can open locally, or get them from erwin.audi.com (or erwin.audiusa.com) for the price of a day pass.

Thank you and the two small twin cable connectors on the back what attaches to them and what are they operating?

SMac770

Ok, looks like you have a non-Bose amp, not the Bose or Bose 6000 amp. https://www.ebay.com/itm/393043654561 So we see where the ASK term comes from.
So 4F0 035 223, no rev letter. Looks like they bounced around between 4F0 035 223 _ and 4F0 910 223 _ before ending on 4F0 035 223 N. That's what had me confused and wondered if you meant 4F0 035 223 G.

So that's a completely different amp unit from the Bose 6000. There's no 18-pin plug on it, as it's not a branded upgrade amp (Bose, B&O, etc). And the 32-pin is:

A - Multi-pin connector, 32-pin, black (T32f)
1 - Terminal 30
2 - Terminal 31
3 - Front left bass loudspeaker -R21- (+)
4 - Front right bass loudspeaker -R23- (+)
6 - Front left loudspeaker (+)
7 - Front right loudspeaker (+)
8 - Rear left loudspeaker (+)
9 - Rear right loudspeaker (+)
15 - Front left bass loudspeaker -R21- (–)
16 - Front right bass loudspeaker -R23- (–)
18 - Front left loudspeaker (–)
19 - Front right loudspeaker (–)
20 - Rear left loudspeaker (–)
21 - Rear right loudspeaker (–)
23 - Microphone 1 (+) from microphone unit in front roof module -R164- ( internal microphone -R74- )
24 - Microphone 2 (+) (not used)
27 - Open circuit diagnostic lead

Not sure what you mean by the back. https://www.ekodily.cz/e-shop/140896...3g-zesilovace/ There doesn't appear to be anything on the "back", opposite end of the 32-pin and MOST.

Thanks that’s really helpful, what are the rest of the pins used for?

Tinkeringsince99

Also pin 1 Terminal 30 and pin 2 Terminal 31 are they the power feed and ground?

SMac770

Yes,
terminal 30 = battery connected
terminal 31 = chassis connected (ground)
terminal 87 = relay connected, general case
terminal 15 = relay connected, specific case - switched on with ignition on

Term 15 is through a relay on modern cars, but I think it got a separate number back in the day because it was through the ignition switch. This "terminology" goes back to DIN 72552 standard, from a long time ago. https://www.arc-components.com/blog/...ion-guide.html

Thank you, and it’s a 32-pin connector, with 1, 2, 3, 4, 6, 7, 8, 9, 15, 16, 18, 19, 20, 21 and 27 used on the amplifier what are the rest of the pins used for?

SMac770

On the unit in your vehicle, nothing.

As in nothing is attached to them or are they blank pins that do nothing?
