Hi all   My cheap chinese dashcam (with separate rear camera) has given up the ghost after 4 years; I'm replacing with two separate cameras, one front and one rear.   There's plenty of info on wiring in the front camera - but does anyone know of any suitable power sources in the rear ? I guess the ideal location would be in the tailgate itself, but failing that somewhere in the rear would be easier than routing all the way through the car.   Thanks...
