I solder and heat shrink all crimps. I like the Delco Weatherpack connectors, they have a rubber seal where the wire goes into the body of the connector making it almost water tight. I also use fuse links on the B+ connectors, but only outside the cockpit. A good way to check your circuits is to use a 12V lantern battery, it has the volts but not enough amps to bring on a meltdown, and will power most all circuits.
