I can only assume (since you failed to mention location and color) that if it is above the brake pedal, and it is red, it is the wire for the rear brakes; part of the trailer package wiring harness.
If so, it runs to fuse 83 in the fuse block. It is rated at 30 amps so it will handle a rear camera. The fuse might not be in the fuse block, but you can always add one, even a smaller one for the camera.
If I'm guessing correctly, there should also be a dark blue and light blue wire with it. The dark blue wire runs to the rear of the vehicle at the trailer harness wiring up under the left side of the vehicle. It is open at both ends. The light blue is the signal wire from the brake lamps, used to signal a rear brake control module that the brakes are applied.
