Mine were disconnected when I bought it. They were an SOB to get latched. I lubed all the latches and tried for a 6 pack to get it latched. Thought I had it. 6 months later I realized that I did not. One day with a helper and some combination of holding the latch, pushing down and forward from the rear while making sure things were lined up, cussing and a violent thrust and it went "click". Locked in tight and I don't know that I'll release it again until I ditch the rear seat for good as I'm scared I'll never get it to latch again. :/
