Connecting a monitor and reverse camera to a motorhome?

Solved

I just bought a 7" TFT LCD screen that looks identical to mine, which is broken.... When I installed it, I noticed that the cable with the DIN (?) 4-pin connector that connected to the rear camera was missing. Now it needs to be connected to one of the 2 yellow RCA jacks, while the rest is used for powering the screen in positive/negative and activation when switching to Reverse. Since the night vision LED camera is no longer powered, could someone tell me where to connect the 4 wires of the cord: +Red, -Black, White, Yellow...? I think:
-Yellow to the yellow RCA jack of the screen (which lights up when switched to Reverse)
-Red+ & Black- possibly to the lighting harness of the camper or to the reverse lights
-White ???
I am afraid to try randomly and risk damaging either one....
Thank you in advance if any of you could guide me....
Have a nice day.

Hello to the rest of my memories of yellow mechanic (RCA), it's the video, okay now red and white is conventional direct current, now for the black, is it the ground or a return from the command?

Thank you Glandu, I know about the Yellow from the RCA Video that I will try by connecting the Black to the -negative and the Red +positive to the reverse light which would serve as the lighting for the LED camera, and finally I will try the White in the same place if it triggers the start.... although the screen already indicates that it is waiting for the connection to the camera (via the Yellow RCA). I hope I won't mess up or maybe just connect the Red to a general +positive like a power supply.... I will try this weekend.

uh ........... the 3 RCA on a TV are
Yellow = video
Red = right audio
Black or white = left audio
Has nothing to do with a power supply !!

uh... there are only 2 RCA Yellow (video) on the screen part that I connected without any problem. It is waiting for the information from the reverse camera that I receive through a cord with a 4-pin colored DIN connector. No sound (specified) on these devices....
My problem is to correctly connect the camera that has been in place for several years to the new 7" LCD reverse vision screen (reverse gear) of a motorhome; the old TFT of the same brand had a cord with a 4-pin DIN connector for linking.

Well, to conclude, I connected by soldering wires to the 4 colored strands of the cable coming from the camera with the Yellow on the RCA plug. I got the video connection by connecting the Black to the ground (negative) and the Red to the reverse light power that I found in the wiring harness... As for the White (?), I left it free, it sparks if I try to connect it to the reverse light as well hoping to power the camera's LED lighting, so no lighting for night maneuvers.... that I had previously!
However, I needed to head back and didn't think to try connecting it to the ground as well, but I don't see why it wouldn't work only at night....
But I have daytime vision, that's already something before finding a solution for the lighting.
