Most of them are connected with seams and the glue seems to work well BUT CONNECT/CRIM SUCK! so that the insulation is not punctured but there is adequate compression. Second, you need quality connectors, NOT THESE! the wire is crimped on one end only and the other end is a lug or spade, etc.). There is a connection at the top of the barrel (the round part where the wire actually goes through and gets crimped). It is very important that both sides of this connection remain connected during the crimping process to ensure a proper connection. When they disconnect (HOW IT DOES), only half of the connector attaches to the cable, and even then it's not a very secure connection. Don't waste your time and money.
