Re: AAW Crimping Question
I used to solder all my connections - partly because I didn't have a proper crimping tool. Once a got a decent pair of ratcheting crimpers I stopped soldering. I read somewhere that in high vibration conditions (like a car) that solder can crack. Ever since then I stopped soldering. I can't imagine how a well crimped and soldered joint could crack, but I've learned to trust the crimp and saved myself the soldering time.
One thing that is good for electrical connections in a potentially wet environment is dielectric grease. It's a semi clear silicon grease. It looks like silocon caulk, but it doesn't harden. If you dope the ends of the wires before you crimp, it will keep the water frome wicking up into the wires. Heat shrink alone can create a cavety that will hold moisture in. If you're going to heat shrink, I'd definately recommend dielectric grease. DE grease is also good for the metal terminal ends. But like most silicon substances, it'll creap out, so a little dab will do. If you get too much, you'll notice the grease leaking out over time and collecting dust on all your wire ends.
Oh and don't forget to pack the back side of your firewall connector with black urethane to keep road grime and moisture out of it.
