I did the same thing on my passenger side. I don’t believe those are soldered in. They just clip in. I took the yellow weatherproofing seal off from the wires and inserted that into the connector then took the wires and put them in till there was a slight snap.Hey all. I’ve replaced my drivers side mirror and have my original for sale if anyone needs one. I pulled the wires out of the connector for the blind spot warning plug so if you are comfortable soldering, it’ll save you $100 if you break the mirror while removing it. See the attached photos. Thanks.
