Ok, So today I am trying to convert a PS/2 Mouse cord into 1 sided S-video plug and then to a Composite Video plug.
Witch would give me a S-video to Composite video converter, Simply.. I’m using a PS/2 mouse cord instead of a S-video cord. The plugs are Very similar (they fit with small modifications)

This is a Mouse/Keyboard PS/2 Plug, think of it upside down as a S-Video.

This is a S-video plug, and the Conversion I want to achieve with the PS/2 plug.
I have stripped the mouse cable to expose 4 insulated wires and 1 un-insulated wire.
There is Brown, Blue, Orange, green and then the Un-insulated wire.
What I want to do is match the colored wires to the Numbers on the PS/2 Plug and then to the S-video plug..
I’m sorry if this is hard to understand, I tried as much as I could to explain my problem here.
Yes I could test for a circuit with a LED and a small power supply/battery. But at the moment I don’t have these on hand and cannot acquire one.
Any help is Greatly Appreciated, thanks :)
