I'm not sure what all of that is, but I would suspect it would be easy to fix. I deal with this on a daily basis. First, unrap all the tape, disconnect any wires that are not factory (it's usually easy to tell which wires are not factory), reconnect any wires that were cut (also usually easy as the wires are color codded. When everything looks like it is back to factory spec, then trouble shoot the problem and fix it. Problem solved. Car fixed. Another possibility is that the wires broke in the door hinge area and someone cut the harness on each side of the henge area and made a new harness for that area. If this is the case, it could be spliced on the inside of the car (as per the pictures) and the other end inside the door. Could also be that the door was replaced at some point and the wires just spliced inside the car. In any case, unrap the tape and have a look. It is fixable.
By the way, What kind of car is it (year and model?)
