DownerMazda you just summed up the total of your lack of getting training in a school by saying how crazy newer vehicle electronics are. They are a breeze to find and solve electrical issues if you know what to look for .
This OPS wiring is a mess of wires and is not something that shops do contrary to one member that say they would take it on. I am sure their shops insurance would have question if that customers car burned down because of a NONE oem wire repair. You may have read I recommend that the OP go to an Auto Electric shop and not a general service shop for the repair. Maybe you didn't notice the current state of DIY mismatch color wires and poor connections?
Now where is that popcorn eating emocon?? LOL
