hey guys. I have purchased a kenwood headunit for my polo, I have also purchased harnesses for my vehicle and the headunit itself. everything matched up with the harness perfectly but the 12v ignition wire was not plugged in to the harness. upon inspecting the harness I could not find where to plug in the ignition wire. I have had suggestions to tap into the cigarette lighter but was wondering if anyone who has done this to their polo suggest how they did it? thanks.
