hi ive bought the correct adapter for my concert 2 cd player , ive got a quattro a4 with a full bose system , ive fitted my pioneer and plugged the things in i ordered (iso) and it didnt turn on , i got my tester and went round the iwres , i have got 12v permenant where it should be but theres no ign live in the audi harness if i join the yellow and red together the pioneer kicks up into life but then i cant turn it off with the key like id want to , ive read the ign live on the original cd comes from the small canbus wires , my question is wheres the best place to get a ign live from near the radio and will it go off on the key , thanks.
