I'd like to add to this post by going one step further. I tow a camper and can see it from the truck's rear view mirror - however; I'd like to put a camera on the back of the camper. I have a class III/IV with a 7 pin wiring harness. Can I do the same thing but use an empty elect port to power the camera on the back of the camper?
I hate not being able to see who's driving behind me and - most important - I can certainly use it to back into the camping spots.
Thanks
