audi a6 2004 wiring

These are the pin outs for most quadlock (MOST) plugs. This one is Audi specific:- audi-rns-e-1.gif. I may have loaded it twice! Looking at rear of head unit with plug removed. Look at the two thin plugs at the bottom, right hand marked C:Ext connector. Pin 5 is + line out, RL; Pin 6 phone speaker + input; Pin 8, line out common; pin 11 + line out, RR, pin 12, phone speaker input, -. Note the NC on left two at the top, these are the rear speaker connections if not amplified. At a guess, U14 St. DSP is the switched amp trigger.

Craig, see my last post, it's Audi specific because you're absolutely right about pin convention not being adhered to but that's car manufacturers for you. Nowadays over here only Ford has an ACC. There's also info for you on Bluetooth integration, now you know why Parrot etc. have line out as well as speaker outputs! Over here I can get adaptor plugs for Bluetooth "fully populated" suits all M/Benz, VW, (Audi and Porsche) and BMW from 05. I also have a collection of plugs to suit that lower right slot, doesn't half save time.

Off thread slightly but see how the Fraud (UK)* version differs:- 168_generic_quadlock.gif *May not be the case now, Fiesta, Focus, and now UK Mondeo = Ford Fusion.
