These are the same OEM butt connectors you will find at VW and Audi dealers, but at a fraction of the price. As per VW and Audi, all wiring harness repairs are to be done with mechanical crimps and are not to be soldiered. A proper crimp is a better repair than a soldier connection. But the correct butt connector must be used.
These connectors have a heat shrink liner with adhesive, so after the wire is crimped into place, a heat gun is used shrink the sleeve and glue it to the wire. This provides support for the wire and seals out dirt and moisture at the crimp. |
