Small wire has 12 volts when the ignition switch is turned on or with the engine running. The large wire has 12 volts all the time switch on or off, this is directly connected to the positive terminal of the battery along with the starter cable and another one that I haven't traced.
The main issue that I see is that the battery/charging light on the dashboard comes on when the ignition switch is turned to any position except the off position, so if I want just the accessories such as the radio the light will be on. None of the other lights or gauges come on just the battery light. I checked my Suburban and that does not come on when the switch is in the ACC position.
