I used this
and ran the cable all the way back to the head unit. I took 12V from a two/one fuse tap, and put it on the audio (accessories) position in the fuse box. I used a 7.5 amp fuse for this circuit. I ran it to a rocker switch, and the output goes two places, i.e. back to the camera, and also to the radio so it knows the camera is on.
Be careful with this cable. Though it is nice, and long enough to come through the rear cab grommet, it is a very small gauge wire, carrying both video and power wires. I broke it the first time, and had to buy another. Protect it with armor, plenty of tie downs, and good routing.
