1972 Fuse Box Decisions

[Dibbons]

I need to add an old school Sun tachometer and a new school air/fuel gauge to the '72 Satellite Sebring Plus (no a/c). The air/fuel gauge calls for connection to a circuit with a 10 amp fuse. The tach instructions don't specify.

So I have little brass tabs I purchased so I can connect the positive wire on the gauges to one or two of the glass fuses. I only see 20 amp and 5 amp in the factory labeled fuse box, so not sure what to do there with the air/fuel gauge that calls for the 10 amp protection. I guess the tach can go on a twenty for now.

I would like to know without testing all day long if one or more of the 8 fuses locations are not even being used for anything at the moment (i.e. "misc" left bottom slot, or "acc" right second from top slot) Does anyone know about how this was set up from the factory? Thank you

Put the tap on the hot side of the fuse and install an inline fuse of the correct amperage for each item you add.
