Another good find... Only snag is you have to have the exact quest name

Once you enter in the exact quest name it will bring up the map with the exact co-ords you need. If you don't have the co-ords mod, you will be able to see the positions easy on the map (which is exactly the same as the one in game!!!)
Not only that, but it will tell you if you can pick up more quests nearby and do them all together!
Check it out. Might just save you a lot of time and frustration.
