Re: ACC fuse circuit
This varies from Year to Year, Model to Model, and Power Accessory Options installed.
In addition some vehicles use both a Power Accessory Fuse and a separate Power Accessory Circuit-Breaker with Power Distribution.
Please specify as to what you have and what you need.

Re: ACC fuse circuit
Here is the basic equipment the ACC ( or Courtesy) fuse powers. This diagram was taken from a 85,.... I think. Later years might be a little different.

Re: ACC fuse circuit
I would disconnect the radio. If your radio has a digital display &/or clock & stores favorite stations, then one of the button for setting time could be corroded & stays on. I had that problem with my radio as it would kill the battery in a couple days.
