Oil pressure gauge, signals lights, wipers and speedotomer not working.
 

I have a newly acquired 83 240D 4 speed manual transmission that runs really good after changing fuel filter. However, several items are not working on the instrument panel. They are the oil pressure gage, speedodotomer, signal lights and wipers. I checked all fuses and they all appear to be good. Is there a relay somewhere that controls these items?
