Generally under the dash is a ground block. There is also a power block where all wires meet for a common power and ground then a larger 8 gauge wire rubs to the batteries to tie into the respective power points.

Your gauges also require a source of the ignition switch so check for loose connections there.

My accessories don't work. #2 battery dead. Charged it for 1 hour and reset circuit breaker. All good. 20 min later No power again. Reset breaker. All good. Anyone have any ideas?
