I took me two days, but finally i finished it.
As suggested, I measured the outputs with a multimeter. And I got 12 V and 6 V in different outputs. I mounted the whole set inside a chassis of an old PC power supply. Now everything looks more organized.
The white and red outputs are for 6 and 12 V respectively. The switch below is to cut off the power input.
I was thinking to use a clasic Audio-Video conector but i am having some issues with that. The wire is quite thin and when connected, it gets very hot. Think i will replace the output conectors with XT60.
Thanks to everybody for the opinions and help. Will post more updates soon.
