TV/Audio-Visual help needed !

Pics attached...

I want to slave one TV to another. I want to connect the 'big' TV to my cable box and then slave a second TV to it. I have the three-wire cable that should do it, and the 'small' [slave] TV has the correct color coded ports, but the 'big' TV has too many and the third color doesn't match (and of course it's the video port).

The idea is that I'll set the second set to channel 3 and use the 'big' TV w/cable box & remote to control the selected channel. Both sets will show the same channel simultaneously, and will flip to whatever channel I want with the one remote.

I've done this before, with my 10 year old Toshiba CRT TV and a small Sanyo CRT. But that crashed and I had to replace both with two LED/LCD TVs. Right now, one receives basic cable, the other gets the cable converter box w/'many' channels.

I'm paying for three outlets & the converter box, so I'm not 'stealing' cable.

I just can't figure out what port on the 'big' TV gets the yellow cable. The red & white are for audio...but which of the blue, green, or other red get the yellow???

Anyone got any ideas???

The slave is for my workshop.

Thank You!
