I am currently installing a Vizualogic dual headrest dvd system in my 02 sequoia and have a couple of newbie questions regarding the wiring for power.  The dvd player is going in the center console and I have already removed it  using the info from this forum.  I can easily get ignition power by tapping into the wires going to the built in 12 volt dc receptical or the power mirror switch.  However, Vizualogic requires both ignition and constant power sources for the monitors.  There is no constant power in the middle console area that I was able to find with a multimeter.  I would like to use the WHITE/ red or WHITE/ blue on the ignition switch harness, but I am not sure where to find it.  I have also removed the kickplate on the driver's side and did find constant power sources in a few spots.  So, my question is where do I locate the ignition switch harness (and how to identify) and can I tap into any constant power source that I find if I do not use the ignition switch harness?  What should I be concerned about if I do tap into another power source?

Thanks.
