Converting a board cam to RCA plug

[MrJack 0]

Hi forum,

 

I have a board cam with servo plug (red, black, yellow). I would like to put these heads on it:

1. RCA phono for the video out

2. Power in

 

I am a beginner and I dont have much experience. I understand that the black ground has to be ground for BOTH power and signal. But HOW do I 'split' the black ground to the two wires? Can video ground and power ground be interconnected in any way desired without frying the board cam?

 

Thanks.

Jack

Jack, can you post a pic?

I have added some pictures. Two being my cam and the last one being how I THINK this goes (found a picture online, however this is an example of left + right rather than video + power)...but I really dont want to ruin the board by playing with wrong wiring

Cut the plug off the 3 wires.

 

ASSUMING the video is the yellow (please check- I'm not sure) I would solder the yellow wire to the lug for the centre pin on the RCA plug and the black to the lug on the outer ring of the RCA. I would then solder another piece of black wire to the outer ring of the RCA and take it to the -ve lug of the power socket. The red wire goes to the +ve lug of the power socket.
