Not having the cabling package, I don't know how to do it with the normal cable features.
However, if you make the appropriate datum curve or series of sketches that are properly lined, you could have a curve interact dynamically by dragging related components. For instance, I can make a spring compress and expand by dragging it but not with Mechanism. So it comes down to how to simulate the cable through curves, and the curve can be the guide for a sweep feature that represents the cable.
