the ratchet and extension is for a kwiee rear slide failure retraction. should be a holw in the middle at the foot of the bed. when the slide is all the way out you have to usde this hole to gain acces to the slide power screw that your adapter tool fit. after you come in a way, you then have to raise the bed and the inside floor and use the tool there. raise your bed and the inside flool and you can readly see how it works. this was not in my owner manual i had to call winne and they took a week to figure it out and sent me instructions that didn't liste my 33v voyage. also i have no hole in the foot of my bed, so if i have problems i wil make an access hole.
