That no 4 fuse services a LOT of "stuff" look on page 8-115
You might have multiple issues
FENDER.......Do you have the "fuel pacer" or whatever it's called option?

DOME.......you checked the light switch? When twisted all the way to the left, this activates the dome lights. First thing I'd do is to disconnect all the door switches.
That is only supposed to be a 20A fuse, but is hot all the time, so it would not be wired to a tach
Check the cigarette lighter, or better, just pull the wire off the back until you get this sorted out
This might be a time to get a tester known by various names. It is essentially an automatic reset breaker which allows you to chase down shorts while having a protective device in the circuit One name is "short finder" and they are made by many of the major auto tool outfits, KD tools, etc

The device with clip leads is clipped onto the fuse holder. It blinks like a flasher (resets) if the short cycles the breaker. The meter device detects magnetism..........current draw.........in the wire harness. You DO have to be able to access part of the affected harness, you lay the meter device against the harness to detect current flow
