Speaking of connectors, our local parts guys have some pretty trick ones. It's heat shrink, with solder in the middle. You just stick the wire ends in, hit it with some heat, and it solders and heat shrinks in one step. I'm sure you've seen 'em. Works great, only problem is it's a one shot deal. If you screw it up, the whole thing is wasted.
They come in all sizes colors, shapes. Just a thought!
