dash grounds are via the mounting of the metal parts to the metal dash, cinch'em down tight .... fuse panels were only installed [on the firewall where you could kick it with your left toe you should see a dotted 'knockout' in the cardboard pad] if there were more than one electric option, like heater, radio, wipers - on the schematic it's called 'accy junction block' or something and is dotted lines - those are available from most vendors and only adviseable if you do have the options, which still could be fused individually with inline fuse holders
the schematic is more readable if you save it to your computer and print it - if you have an image editor you can also save it, rotate it, and enlarge it, but printing it should fill a page same as in the manual, a magnifying glass helps
