Not sure if yours is the same, but mine automatically selects V1 when the Blue
Wire is OPEN and V2 when the blue wire has +12 V.  I hooked mine up to a DPDT
switch with a center off position so I could have ON-OFF-AUTO.  The Blue wire
is hooked up to the common terminal of them switch, the Reverse lights are on
one leg and a +12 constant source on the other leg.  I really like being able
to flip it on any any time I want while pulling the trailer.

  Hi guys..

  bought an E-bay special backup camera system for my Suburban...  wonb t be
  installed permanently but used in different vehicles to hook up trailers.
  Will fab a bracket to hang the camera over the tailgate and the monitor
will
  be in the cab.

  there is a 7b  monitor with a red/black for 12 volts  and two video feed
  lines for V1 and V2.   and a Blue wire they tell me to hook up to the back
up
  light.
  there is a camera with a red/black  for 121 volts and a video o/p cable
that
  goes to V1 or V2 on the monitor.

  Ib m assuming the blue wire is a trigger to turn on the camera when
  backing... but I want it on all the time so I assumed to hook it up to
12volt
  source.

  all I get when hooking up as above is a white light flashing on the monitor
  and no video at all   Ib ve tried it with and without the blue wire, blue
  wire to ground and blue wire to 12volt +

  nothing works..... any backinup gurus out there ???

  I can email a sketch of wiring if anyone wants it

  thanks
  John
