Dave, I wish we'd spoken a little earlier.
I saw that, but when I asked the tech he said it wasn't for camera power, oh well, that's what I get for not testing thoroughly. It wasn't that hard to extend the power cable, but I would have preferred if I didn't have to. It would have made the install cleaner and easier. I just used a piece of AWG20 and electrical taped it to the video line every 6 inches or so. Not worth it to redo/undo it now.
If you examine the Rydeen camera harness, there is a plastic junction that joins the fat cable to the camera on one end and to the 3 cables (power, ground, coax video) on the other. So I naturally assumed that the coax was video only, as you pointed out the confusingly named Anode power it the only clue and no help.
Hope this saves someone a little bit of time. I'll add this to my other post.
