Been searching the forums for days now. I know I can tap in behind the instrument cluster but it is stuck and won't come out more than a couple inches. I read a couple posts that said they tapped into a blue/white wire behind the driver's side kick panel. I tried a couple blue/white wires there and neither worked. Any idea which wire in which connector down there would work for me? I'm installing a Pioneer AVIC-X920BT and this is the last hurdle.
