Don’t forget to work your Under-Hood Fuse Box with a Lighted Test Probe to eliminate most of the Circuits NOT affected by any damaged wiring. Any Loss of Continuity will help with pinpointing certain Circuits, Wire Bundles and Harnesses and Plastic Weather-Pack Connectors that might have become "Snacks for Mice".

Last But Not Least... Regarding the P0335 Code... THIS Thread includes information from @Mooseman that touches upon the subject:
