We just installed the jack and the directions were okay, a few more diagrams would have been helpful. When I had watched videos on others installing the unit I only found one showing how to install the electrical to the battery and this was my worry and this one did not show the red wire fuse so we had no idea it would be in the box and this was a worry because we were doing it ourselves. I finally found a video that showed that you cut the red fuse wire in half and install the enclosed connectors, but it would have been very helpful if it was in the directions. So when you cut the red wire in half you attach the Ring Terminal to one end and the black wire using the double connector to the other. Sorry I don't know the exact name for the parts. Clap each of these and then we used electrical tape to secure. Then you attach the Ring Terminal to the positive post on the battery. Also you need to sand the paint at each holes to get a good metal to metal contact for grounding. One more thing the directions don't tell you to install the star washers prong sides down, watched videos for this too, it digs into the metal for grounding. These little items are very important because if grounding and wiring isn't don't properly it is dangerous. Now that we were done the jack seemed to work fine. Only used it once so far, but so good. If the company did a video from beginning to end showing and explaining the whole process they would get more sales because one of the reasons I choose this one is an individual did a video but it wasn't complete but better then the others and he made it sound easy to install.
