'latches for the rear cover' are you referring to the latches that hold down the tonneau when the top is down? How does this 'bump box' work?? how is it connected??I pulled 4 motors out of my top 2 on each side and have a bump box to jump the latches for the rear cover. Takes about 2 minutes to put down the top would be nice to push a button but not a big deal to me
