Review on Waterproof Electrical Connector Automotive Connectors Replacement Parts ... Ignition Parts by Deonte Bates

She was trying to hook up an LED tail light on a golf cart with brakes, turn signals and daytime running lights. I needed 2 sets of these wires. After all the connections, not a single lightbulb worked! After about an hour of troubleshooting I found that one of the connectors in the wire harness was not connected to a wire at the pin end (BLACK for GROUND). I think you get what you pay for, they are not high quality but will work. Needless to say my first experience with them isn't great, don't expect to have to test them on every wire and connector pin before soldering them to the harness for continuity, but it might be worth doing, if you want to avoid later troubleshooting. I'm also not sure I would trust them if heavy rain or water can actually drench these ports without concern. Let's just say I wouldn't submerge them in water like a boat trailer unless you want to deal with corrosion.
