Review on 🔌 ESUPPORT 4 Pin Way Car Auto Waterproof Electrical Connector Plug Socket Kit: 10-Pack with Wire AWG Gauge - Ideal for Marine Use by Kevin Mariappan

These are my favorite connectors for connecting car accessories. I've used them on both my truck and ATV and they haven't let me down yet. My quad sees mud and water regularly and the gaskets on these ports do not leak. I use a dab of dielectric grease before assembling them, that might help but I would do it for each connector. My last project for them was a custom hanger I made to install night and backup lights on my new truck. Each suspension leg has its own connector so I can swap out the bulbs if they burn out. They've been under the car for a month with no problems. If you are looking for simple and cheap two-wire connectors at a good price, I recommend them.
