1985 190E Electrical Help/ Relays?

[montanass]

I've got an 1985 MB 190E, and I'm having trouble finding a reason the radio, power seats, power mirror and fog lamps don't work. All of my fuses are ok, have power and are not blown. I'm thinking the car may have a bad relay, but I'm not sure which one runs these functions. Does someone have a wiring diagram or a fuse/relay arrangment diagram. I don't have an owners manual, and the lid for the fuse box only has reference numbers for the fuses, but nothing for the relays!?! Any help is sure appreciated.

Thanks
