first pic looks like your relays for things like horn & headlights
2nd pic is your bulkhead connector which goes to either your fuse box or the harness of the steering column (for ignition switch, etc)
the third looks like it might be the starter solenoid or some other sort of relay/solenoid
your wires for most of your gauges gauges should (not 100% sure on the earlier years like yours though) go through a grommet in the firewall somewhere closer to the middle... closer to your valve cover or intake.
