Locate connector X6964 (in E-box) where all those red/white/yellow wires are bundled together. Take them apart. Measure which one of them comes from the fuse supply. For rest of them measure resistance against ground. When you find which wire is shorted keep it separate. Connect all the rest back together and check with diagnostics which component is missing. After that you start investigating the faulty component or wiring from the bundle to that component.
