Which one is position 2?

Sorry to be asking questions as my first post, but after 1 hour of google I'm no closer to an answer & someone here must know. I've found loads of info on the fuse boxes, but nothing on the relays. There's 2 relays in the engine bay fuse box (I have no idea what they are for, but I assume they will be for something more general like lighting), so where's the rest? Specifically where is the relay coolant pump relay? Also does anyone have a graphic indicating which relay is for what? as that would be handy
