Anthony,
I know you asked Johnny but I'll weigh in here too (some fatherly figures around here have called me Johnny Boy) /bcforum/images/%%GRAEMLIN_URL%%/grin.gif
A properly crimped connection is very good. It is a cold weld connection and should last "forever".
I don't want to argue crimped vs. soldered because both can be good or bad depending on how well they were done (plus I'm not an expert!). But I've been told that crimped connections are used routinely on vehicles, aircraft and spacecraft.
I checked each crimped bullet on my BW harness by lightly pulling on them. Yes, a few were loose (which really is unexceptable from a QA standpoint) and I replaced with the original solder type. Also, I put a small amount of di-electric grease around where the wire inserts into the bullet and some more inside the connector when making the final connection (important here to use the special pliers or small channel lock type pliers to full seat the bullets into the recepticles). The idea for the grease is to keep out air/moisture since air/moisture can lead to corrosion.
Hope this helps,
John
