We just installed a Premier Power Welder on a 2008 JK. I've got to say that this thing is bad ass and works far better than I ever would have expected. We made a detailed installation video as we found that there was lacking video on this product. Hopefully this helps anyone interested in adding an on-board welder. Kind of long but we went into as much detail as possible including how to operate the unit and how to advance your idle speed for operation.
