I needed these cables for a portable winch application. The cables looked great with t he exception of some missing heat shrink around one of the connectors. I contacted the seller requesting some heat shrink tube and they sent me an entire new cable set. The new cable had the same missing insulation so I am assuming that's just how they are made. I was able to disassemble to connector and simply apply some heat shrink tubing. I then installed the cables on my truck and it works perfectly.
