Hi Have just got a ex-demo Prius and loving it.... But I want to hard wire a speed camera detector - essential with points on my license already (??!!) - I have run the wires from the windscreen to the rear of the 12v socket under the gearstick....but am struggling with no multimeter to work out the wires at the rear of the socket....so simple question is....two wires, one solid black, one white and black...which one is earth and which one is switched 12V??? Please help me!!!
