Review on 💦 Waterproof Electrical Connectors Kit - MUYI 5 Sets 18AWG | 1.5mm Series Terminal | Rubber Seal | 10cm Wire Weatherpack Connectors (4 pin) by Dangelo Toliver

I used two of these on a recent lighting job and had a problem with one of the connectors. After an hour of troubleshooting, I found that the actual pigtail wire on one of the connectors was not connected inside the molded plastic on the small pin end. It just so happened that it was a ground connection, so nothing worked! Turns out I had to pull the plug out of the socket and re-solder the wire to that pin. You wouldn't think you would need to do this with brand new connectors. Recommendation: Quickly check each pin and wire before using each connector, it can save you a lot of time!
