Wanted to know what everyone is using for waterproof connector plugs. Right now I have some cheap ones off of ebay and my searches have not turned up much. They are going to be used on a back rack for a truck.
You can always try a marine supply shop... but if you can do without the plug.. solder and Heat shrink is the way to fly.. I've seen those other water proof conectors fail, and they are really way over priced
Weather-pack connectors, which are what are pictured in dmathieu's post. Can get them as single pin all they way up to 6 pins and handle up to 12 gauge wire.
Also not sure what you're using them for but the Weather-Pack connectors are rated for a max 20 amps. Amphenol ATP's are rated for 25 amps but only offered as a 2 or 4 pin connection.
