After lots of big holes in the back of my TJ here is the finished product. Not a very hard install but cutting a 4.5" hole in the back of my almost new to me TJ was pretty difficult(mentally :p ) I used 2" LED's for the side marker light and my 3rd brake light. THe reverse lights are 19.95 walmart driving lights.
Big thanks to Artie for braving the rain to help me with the install.
