braveheart1969 Posted February 16, 2020 Share Posted February 16, 2020 I have recently bought a B7 3.0 Tdi cabriolet and I think it is the best car I have ever owned. The only issue I have with the car is that the previous owner has cut off the factory connectors to the audio system at the rear of the head unit. I am left with bare wires and know clue of the colour codes. Does any one have any wiring diagrams or pin outs that include wire colours? Thank you in advance.

Magnet Posted February 16, 2020 Share Posted February 16, 2020 Hello Rab, What are you trying to do - return the car to original in terms of its audio equipment or not? Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
braveheart1969 Posted February 16, 2020 Author Share Posted February 16, 2020 Hi Gareth, I am trying to fit an aftermarket head-unit but can't make head nor tails of the wiring. I am guessing the colours are Audi specific. The original stereo was a RNS-E if it helps. Quote Link to comment Share on other sites More sharing options...
Magnet Posted February 16, 2020 Share Posted February 16, 2020 Thanks Rab, I could well be wrong, but the availability (and understanding) of wiring diagrams is not what it used to be, but it’s quite possible that someone on here might be able to help you. Get it wrong and trouble lies ahead! Options if you can’t get help on here:- Obtain an original plug and it’s short length of wiring from a breakers ( register your want with Partsfinder or similar). Connect this plug colour for colour into your harness, and buy the adapter plug to link your new set to the original plug. Or seek out a trusted local audio specialist and get them to connect up your new set to the chopped off wiring. Probably nothing in it cost wise. Sorry I can’t help you directly. Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
braveheart1969 Posted February 16, 2020 Author Share Posted February 16, 2020 Thank you for that Gareth, I'll jump on some breaker sites and see what I can find. Quote Link to comment Share on other sites More sharing options...
