Can someone help me with adding Composite Video RCA to this vintage Hitachi K50L with tiny CRT TV?

I want to do a mod to this cool vintage multiplayer and would absolutely love a bit of hand holding. After seeing some YouTube videos on it it doesn't seem too complicated but it's still more than I can figure out on my own.

I need to find out where to tap into to access the video output and also audio. I see on the TV schematic there is "Q701 Video Out" Is that where I tap in?

Also I assume I would want to add resistors or caps to aid the mod, but I'm not sure.
