TFT LCD display

I have 7 inch display which I used in my car almost 10 years back I want to use it with my Rpi3b+. I tried changing various display modes in config.txt like sdtv mode =0 and other numbers. None of them are working. Sometimes screen blinks but it doesn't work. This display has two video inputs and works with 12v seperate power supply. power supply and inputs I am using composite cable for connecting rpi to this display. Composite Cable

I tested with various tutorials like press shift key until green light stops blinking then press 1 2 3 4 which will redirect output to composite. It didn't work. I tried hdmi_ignore_hotplug=1

None of these are working. Can somebody guide me how to make it work. TFT LCD works perfectly with my analog camera.

There are (at least) 3 conventions for the adapter cable, most commonly available unsuitable.
