Steve- You could certianly arrange a generic blend of different cables through out the ship. Use different colored thread or wire for fire hose (light gray), cables (dark grey), etc. You could paint the fire spindles (or reels) red, the cable spindles gray, as they do on some ships.
I always lean towards a little artistic license in times like these, helps keep the creative juices flowing as it were. Historic accuracy is great when the data's avialable, but in it's absence why not have some fun. It's all part of being a "project manager"
