Ok, Picking up a hardtop for my TJ. This top is equipped with defrost and possibly a wiper. Question is what will I need get these options to work in my Jeep? My jeep never had a hardtop with defrost or a wiper nor does it have and connections at all for these options. The donor vehicle was in a wreck and being parted so I am pretty sure I can get everything I need. I can only assume the washer fluid bottle is of a different design to send fluid to the rear? Wire harness of some sort going from the rear glass to a switch? Just want to make sure I have a list before I head over to pick it up. Thanks..
