Eric, I'm finally getting around to installing the cameras and monitor in my NX (now that it's back from the dealer's and I have available time to work on it). You'd mentioned that you just ran wires for the rear camera in the rear window opening (open window, feed wires, close window and route wires), is this correct? I had to wade through a bunch of this thread to find a picture showing the rear camera. I believe that you had suggested just attaching it to the black plastic underside of the cab top- is this also correct (what you did)?
Did you ever installed a front camera? I've looked at what a lot of folks have done and I'm kind of wondering about mounting on top of the brush guard: I realize that it hinges forward and that I'd have to provide extra lengths to the cables. Seems that this would provide for a good view.
And for something completely unrelated... Where did you mount/bolt-down your sacrificial anode?
