The only tricky part about this swap was the defrosters - CJ's run em thru the windshield frame, wranglers run em out thru the padded dash. I was swapping wipers and heater, and building a dash from scratch, so it was no big deal, but you'd probably have to cut new defroster vents into the wrangler windshield frame.
They wired right up to the cj wiper switch, the windsheld frame lines up perfect, i even used the windsheld glass and gasket from the cj in the wrangler frame. Oh - don't forget to transfer the vin# plate.
