Sony bullet camera wire colours

[steve-V8s]

Have a small Sony bullet camera which has (had) a 4 pole 2.5mm jack plug attached to plug into a mini recorder. The plug has got mangled to the point where I am not able to determine which of the 4 wires went were. A quick web search has failed to come up with what is what. Anybody know which wire goes where ? The options are Red Yellow White Black

I have an older Sony bullet camera (from DogCam) and it's

Yellow = Video input
Red = Right sound channel
White = Left sound channel
Black = power
