Sony rear camera questions

We have a Sony rear and side view camera system that came installed on our rig. The picture from the rear only is distorted (picture below). The side cams are fine so I have to guess the rear cam or a connection to it is bad.

I took a look at the connection on the camera and there does not appear to be a plug on the camera. When disconnecting what looks like a plug there are just small wired going directly in.

I got to the back of the monitor and there is one video plug and one audio for the mic in the rear cam. Since there are three cams, where do all the wires meet? Something must be connected to the turn signals because the side cams come on automatically when they are used. I also will assume there is some type of plug like the RCAs behind the monitor somewhere in the rear.

TIA for any help.
EDIT: I found out the thing I am looking for is called a video switcher. Now to figure out where it is hidden.

Found the switcher. It was under the dash on the right hand panel you face when coming in the door. Attached with Velcro to the back side. One cut on my wrist and one on my nose while digging

No help there though. I can switch a cable from a side cam to the rear input and get a good picture. Next attack will be to search for another connector for the rear cam and replace it if necessary.

make sure you have a trigger voltage for the rear camera feeding the switch box. The rear camera has about a 2' lead and then the connector is going to be inside the rear cap of the coach. You can remove the camera and plug it into the switch box to test the cable. Good luck and keep us posted.

I got the cam removed and plugged it directly into the video switch box. No joy. The picture is the same.

It appears these cams are no longer made. They are 8.1V. Who ever thought up that? They only possible direct replacement I could find online costs more than an entire new system. Is it possible to use any IR camera even if it had to be separately 12V powered?

Adaptability would be of huge convenience. I am sure that all the monitor is looking for is a video signal from the camera. Someone may have come up with a conversion kit if you want to research that for us and let us know what you find.
