Just did this install today..... and already can't remember the brand name of the camera. It is meant to be used on rear license plate area and is wireless from camera transmitter to inside monitor.
After much surmizing..... I removed the third brake light lense. Found enough room to tuck transmistter and all wiring back inside . Connected power and ground to main plug supplying brake lights and load lights. I can use the cargo light switch in truck as on/off for the transmitter. I attached camera , centered just under the 3rd brake light lense with two sided 3M tape. Camera is almost unnoticable on the tinted window, and does a good job showing 5th wheel(which was not visible over my tonneau cover previously). Also does decent job as rear view... .
The submersible rating of the camera hopefully will withstand the weather... ..... The cheap rear camera's avail without this rating will not last a year on the license plate in our weather.
