Hello!!
i have AudiA4 TDi 1997 European with board computer (VDO).
When i buy car there wasnt AUDI car radio.
now i get Audi concert and cant find 3rd conection for radio
(1st-power, 2nd spikers, 3rd lines for displaying RDS on dashboard)
So need to find few wires from dash to radio.

 

it should be part of one of the other plugs...

 

But hire in car are only 2 conectors. power and speakers no 3rd conector. So i must get new wires ( wires are probably cuted off somwere in the middle ).
