There's one on my NP205 also. Right now the speedo cable is too short to connect to it, but soon I should have the proper length cable and hook it back up. I think its a good thing to have because as you change tire size or gear ratios in the diffs., you can adjust for those changes with that little box. All you have to do is take the tire size info and diff. ratio info and that box to any qualified speedo repair shop and they can change out the internal little gears to make your speedo dead on.

It's a good item to hang onto.
