I need help identifying which wire is the positive power wire for either the clock of the thermometer for an '03 Camry. I am installing a Pioneer AVIC-N1 and want the video to be able to play at any time. So instead of tapping the power for the hand brake light, I figured I could tap the clock instead since it always has power. If anyone has other suggestions for wires to tap instead, let me know. Thanks in advance.
