I was able to take out the reverse switch with a 22mm box wrench but only had the room to do so because of a CAI. It is made of "brass" and is soft so I wouldnt recomend using plyers. Anyway I played with the ball berring end by pushing it up and sprayed carb cleaner into it then rubbed it on a rag, just like a ball point pen, until it left no marks. Put the thing back in and what do ya know I have backup lights again. I tested it about 5 times and it's still working so we'll see how long it lasts... :thumbsup
