Sorry don't know about the wire but might have a suggestion for the undertray. One of the 2 rear fixings on mine was held on with a cable tie when I bought the car, this was when it was only 2 years old. Had a look and could see the nut on the inside of subframe was missing.
When I fitted the aluminium undertray I was able to drop a bolt down through the hole, there's a hole just to the rear of the fixing point just big enough to do the needful. Then a nut to lock it in place, a washer either side of the undertray and a nut to hold it all in place.
Having said that if it's just your bolt that's stripped you'll be able to pick one up anywhere, if the nut inside the subframe is stripped drill/knock it out and do the above. If the nut has come loose and your bolt is just turning you should be able to feel it through the hole I was talking about, maybe you could hold it still with your finger then undo the bolt.
Loose - not close, compact, or tight in structure or arrangement
Lose - to part with or come to be without, as through theft, accident, negligence, etc.
