Ya i would say spend the extra to get the security of everything working and all your wirering will be new and not torn up by someone else. And you wont be missing anything. When i bought mine on ebay i was missing one wire that conected the head unit to the hideaway, since i bought it brand new in box from a guy that owns a sterio shop he sent me one for free from the pioneer factory. that one wire was like 60.00 bux. Ebay can be tricky just make sure you know what you are bidding on. I have been screwed on there a couple of time just glad i got my money back.
