First problem is powering the system ,with the TX i got a cable that have a Yellow ,white for Audio Video
And a red banana like plug (maybe power?)

Some pictures of you simplest setup will help me !

It looks like my FOX Rx, it has a standard DC plug with the V+ on the central pin.

You should be able to check the polarity by looking at the power adapters for the symbol which specifies if the tip is positive or not. It also looks like my FOX rx, which also has V+ on the tip (central pin). Then you can hack a connector (I cut one off of the supplied power adapters) into something which connects to your battery.

the camera is this
and i'll use it standard with her battery, i will not make any mods , just connect the video out to the TX... the camera is 5v

In your pic you mentioned connecting video + to audio, vtx and battery+. Where is the video+ coming from if you are only connecting the video signal and -?
