Voltmeter Wiring Diagram Wanter

The easiest way would be to run a wire from the clock to the "always hot" side of the cutoff switch.

On the Mini I have a battery cable disconnect. I have a 5 Amp fuse wired in parallel to the disconnect. That allows me to keep the low current items running with the battery "disconnected". However, if someone were to try and start the car with the battery disconnected, the 5 Amp fuse would blow. So... I still have an anti-theft disconnect while the accessories can still be powered up.

For clarification: could I have a wire coming from the Gauge to the positive terminal of the battery and a light gauge wire with fuse to the ground? The gauge has a wire to ground already. Car is Negative ground.
thanks

No, you should have the fuse in the positive wire to the gauge, and it should be near the battery. That way, if the positive wire shorts out on the way to the gauge, the fuse will blow instead of the wire burning up.

Okay, no problem since I was considering doing that. What about the negative wire...install a small gauge wire from the Neg on battery to the Ground by the cut-off switch?
 
Patrick:
What size fuse do you plan on using to protect the Meter??

DK's solution as stated is good.

I tried a 5 Amp and it worked. I tested it by turning off the battery and noted clock still working then I turned on the headlights and the fuse blew, which it should have.
