12V source for rear view camera on Ford E350?

I would have thought the wire harness between the monitor up front and the camera in back would include power. If this is truely the case, then 12v power would be routed from the front fuse panel to the monitor and then you run the kit-specific cable between the two devices.

Right?

It's not the center, it's pin #4. See the chart above.

If you have a rv plug in the back, check center for hot and take it from there that is really the easiest if you dont want to tap into the backup lights.

I pulled power for my wireless camera from the front fuse box and mounted the transmitter midway back to get it as close to the monitor as possible. If you want to pull power from the back and you have a rear mount generator you can pull power from the hot side of the generator starter connection. I did that for my trailer plug stop/turn relays. I used a 10 amp inline fuse.

I think it would depend of whether it's a _wired_ or _wireless_ camera system. Mine (not an E-350) is a self-installed wired system, almost 8 years old now. The camera power & ground comes from wires in the cable that carries the signal; it gets power from the monitor, which comes on with the engine.

My 2010 F150 Truck has a rear camera factory installed. First one for me to ever use. This is great. It is mounted on the rear tail gate and shows the trailer hitch. I can actually see the trailer hitch move directly over the trailer ball mount.


It too is wired to activate when I am in REVERSE on my truck. When activated my information screen becomes a rear camera video screen. My setup also has calibrated foot marker bars that beep at different rates when coming into view. This has sure made hooking up to my camper trailer a quick and easy first time operation.

There has been several incidents I would have liked to have the rear camera on without being in REVERSE. If I was installing my own I would look into have full control of my rear camera. The only drawback I have is rain and sometimes close vehicles with their lights on at night causes flare-up on the screen.

I suspect the newer vehicles will already have a factory wiring cable installed for the rear back-up cameras.

My aftermarket backup camera is powered strictly from the back-up lights. Put it in reverse and the camera is powered; I just ran a wire up to a tail light for easy access.

I guess the answer to the question depends on the camera and what it requires.

I ran new wiring all the way up to the cab so I could control my
camera at will. I really like it this way.

The way mine was wired from the factory, the CAMERA is powered from a switched hot wire. The MONITOR in the cab is powered by a switched hot wire, but is activated by the backup lights. I also have a switch on the monitor to activate it even if the backup lights are off.
