They're pretty good quality and I think they're waterproof - I've used them to replace all the connectors on an old bike - although to be honest I haven't avoid driving in the rain. There are no instructions on how to assemble them, but you will eventually get to them by studying them carefully. I used sets of 2, 3 and 4 pins and they were all pretty much the same. I'll use the rest for future projects like this one.
