4 or 5 point harnesses...

Where do they connect to? The seats?

I've seen one that went to a bar crossing the rear seats.. is there a way to connect them and still keep the rear seats functional?

You either want to connect the shoulder straps to the floor (as long as the holes for them in your seats are well above shoulder height) or to a bar (which is what you would have to use if you are using stock seats.

THen the side straps would hook to the floor on either side of the seat.

Then, if you get a 5 pt. harness, the 5th strap hooks to the floor in front of the seat, on the floor.

Ok just making sure if I went with them eventually that I could still use my back seats.
