when you work on an engine (or anything really) that has a lot of similar looking hoses (vacuum or not) that plug into other similar-looking nozzles, how do you keep them all straight to avoid mixing them up when you reassemble it?

what is your method? do you use a digital camera? do you use pencil and paper? do you somehow label what goes where? how do you do it?
