One of my reverse sensors fell off ,when the rear bumper was loose I have it and its a 2 wire one but it only has one proper red wire and a really really thin screen for other wire its so thin that as soon as you expose it from the outer plastic sheath it just crumbles . I used to be a prototype wireman in my Young days and i have never seen a cable as fragile as this or so impossible to hold or solder ,,, any ideas
