Worried you as an attitude for soldering, stuck there in the connector. The plug has a small round hole where the cable is angelotet. There tuck the Lötkoblen and about 30-50 seconds. Wait until the plug has good aufgehitzt. Then from above the solder fill (quiet a bit what pure) and equal to the cable tuck. Soldering iron out and after about 1-2 sec. Takes up the solder and is a perfect soldered cable.
