Hello every1, I've just recently found this forum and I'm hoping someone here can help me. I bought a 2001 300M that didn't have the underhood fuse box cover, and now I'm having some electrical issues and need to know what relay does what, so I was hoping someone could upload a picture (or diagram) of that cover that shows a description of those fuses and relays. Thanks

 

It would definitely be worth your while to track down a cover and keep that box closed up. Electrical boxes do not do well when water and dirt can migrate in there.
