Thanks Carey.
The blue crimp on spade connector are a very good brand that I've been using for years, and I've never had any problems with them as far as corrosion as I always apply a little dielectric grease to the terminals, I also always twist the wires and solder the ends before inserting them into the connectors and crimping them, and as far as sealing them up where the wires go into the connectors with shrink tubing, the connectors are still open on the other end, and it's behind the side cover as well protected from the elements.
