Wanting to put a battery disconnect switch in a Peterbilt 379. Any tips? Have the 4 battery setup. There are 2 grounds coming off going to the starter. Can those get tied into one switch or do I need 2 disconnects? How do you size the switch, cranking amps for all 4 batteries combined or just 1 battery cranking amps? Where is a good place to mount a switch, was thinking below the drivers door.
