Hello, <p>I am trying to connect an ipod interface cable (Blitzsafe) behind my Volvo radio (1998 V70 XC, radio model 816?) and I am trying to locate the cable going into the radio harness which has a constant 12V power. I will tap into that cable to power the interface. <p>I dont have a voltmeter and I dont want to disconnect the cables (cant remember radio code). Does anyone know which colored wire I should tap into? Thanks!
