2001 e430 horn issue

neither one of my horns are working and from what i've seen either the fuse or the relay (or both) are the culprits. the operator's manual is useless as it identifies the fuse location as #41 or #42
which do not appear anywhere. similarly, i'm not entirely sure which relay is for the horn; whether it's yellow, green or black.
any help with fuse number location and/or color or part number for the relay would be appreciated

The relay is located within the front SAM, however don't forget to check the horn connectors as you may find loads of corrosion. Go to any dealer the relay is cheap and they will tell you the location!

fuses: check under the large plastic hatch in the engine bay, just in front of the firewall on the passenger side
