Hi

i've read a few different threads on this matter but haven't found the answer I'm looking for

my mum has a 2005 Audi A4 cabriolet

the radio has a poor connection when you listen to FM channels. (Fuzzy)

did the usual check for broken wires in the boot lid rubber grommet. Found a broken wire which led to the beige connector on the booster. Repaired the wire.

it appears I may have more than one fault here

id like to know which of the 2 wires sends the 12volt feed from the back of the radio to the booster unit? Is it the beige connector or the curry connector. Many thanks
