Screw connections unless you're sold on keeping things stock, solder up your connections corrosion can't get into soldered connections. Anything you're not gonig to solder together slather with a good coat of dielectric gel, this stuff helps keep corrosion at bay. Heat shrink tubing is a really good idea, as is blocking off anything water can get into that it shouldn't. I'm a year round rider (granted its southern California) and I get quite a bit of moisture on my way in to work for a good part of the year. When I pulled apart my wiring with my last redo of the bike I was surprised at how many of the connections looked crappy. Tracking down a bad connection in the dark or rain can be miserable at best. Next redo on my bike I'm going to eliminate as many connections like this as possible, I haven't this time around because I know I'm going to be pulling everything apart again within the next year or so.
