2013 sequoia Camera harness

I'm looking to install a backup camera on my 2013 Sequoia without JBL or Navigation. I have found the harness plug at the tail of the SUV where a camera can be plugged into and its already wired through the SUV. I bought an OEM camera and all I've got to do more or less is plug it in and go. That being said, I have a few questions. I have removed my factory radio and unplugged the harnesses and soldered on the new wires for an aftermarket display radio. However, there is no wire harness for the back up camera even though there is a plug for it in the back of the vehicle. Where does the other end of this harness come out at? I have searched online for DAYS and have not found a wiring diagram or so much as a YouTube video. Please help.

 

On my wife’s 2008 sequoia the reverse harness is in the overhead console. It was hidden behind the compartment closest to the rear view mirror/windshield. I don’t remember what was there originally,it may have been some flip down little mirror to see the passengers in the back seats.

I added on the reverse camera and tiny flip down monitor that went in its place. It was plug and play.

I thought it would be behind the radio as well..but it was not.

 

I looked under the overhead and found the plug for the camera display. However, it’s a 14 pin plug and I am unable to find a wiring harness adapter anywhere for it. All websites I go to say I need a 16 pin harness with a 6v reducer. Do you know of any websites that would sell a 14 pin adapter harness? If not, how would I wire this to my radio display?

 

I am going to and you a private message in this subject. Years back i found a guy who could make a custom harness to go from the overhead to behind the radio
