Make new ends to wires,when you find the broken ones youll cut into it anyway,be sure to splice a new bit in, dont just join the 2 ends as itll be shorter than before. I remove the whole tailgate trim panel and release loom from clips,this allows a bit of movement and gives more to work with The boot was in the way, i just cut it along its length then bound it tight with tape when finished. Inside the wing you can release loom from clips to pull it up a bit but i found it to be a PITA and didnt bother
