This is the before scene of my splicing party. The big harness to the rear where it enters the rocker cavity. Eight wires either badly nibbled or severed.
Thing is, after I cut away the mouse chewed parts, I now had gaps in the wiring to fill, which meant two splices and a short length of new wire between them on each damaged wire without bulking things up too much to stuff it all back in.
Don't forget to slide on the heat shrink tube before your solder up your connections.
