I retore Gen2 Camry's exclusively for a living . I also do repairs.
I have this request often because the seatbelts or something don't work and it often is just a busted wire in that rubber boot going from the door at hinge area.
I just pull it completely out of car and fix the wires and tape up the harness skipping the broken plastic harness mounts.
I guess you need to find a boot or I could send you one. Don't just try to wrap the wires as moisture will get in the door or fuse block area and cause more problems.
