I just bought an 02 Wrangler (TJ), and I want to mount my 7'4 Homesteader plow on it. Using the eMatch system I have the Mount Kit number and Electrical Harness to order, but the system doesn't specify the isolation module. Is this a problem in their system, or is there something about this vehicle that doesn't require one? I'm trying to order the right parts for it. I don't want to get hip deep into it only to find I'm missing something important.
