Each of the red and white wires should be a co-axial, i.e. you need to strip each further until you have the centre core and the screen.

If you have access to a test meter, "buzz out" the cable to find out which centre core is connected to pin 3 - luminance.

Connect that to the Y terminal. Connect its screen to the earth next to it.

Connect the other centre core to the C terminal. Connect its screen to the earth next to C.

In the absence of a test meter, I would guess that white is Y and red is C. Or as Scott suggests cut the plug open.

If that doesn't work, swap them round.

You're unlikely to get a B & W image if they're the wrong way round as there are no syncs on the chroma (you might get some sort of image). You would get B & W if the luminance was connected correctly but the chrominance wasn't.
