I purchased a new trailer wire end connector for my utility trailer 7 wire flat that plugs into rear of pickup. I purchased Hopkins Endurance 7RV metal Connector#48510. This connector is metal and has two piece pistol grip handle. I followed all instructions. The last step was to apply the two piece handle on frame over wires inside. This is problem When you put them togather and apply supplied screw you are to put screw thru inside 7 wires that you can not see. when I turned on I got instant smoke/fire blown fuse. The screw went between ground&hot wire. Delay in short could have caused accident or unattended fire. Product reviews show other owners having same problem as I experienced.
