I just picked up an a3 1.6 as a cheap daily commuter. I tried fitting my clarion head unit as there was no head unit in it when I bought it. It has the standard iso connectors which I plugged in and left one small brown connector with 1 wire and a red connector also with 1 wire. I get no power at all to the head unit. Do I need a wiring harness and if so can anyone tell me which one?
Thanks.
Thanks.
