71 blazer wire harness questions

Heat shrink over them does help a lot. One trick my dad used to do way back when, (he hated soldering also) was to fill them with silicone, then push the wire in and crimp while the silicone was still wet. Never saw any of them go bad that way either. Just need to get a good crimp and a way to keep the moisture out.

I may have gotten a bit anal when I did mine. If I needed to use an eyelet at the end, I'd pull the plastic off then crimp, then solder the wire to the eyelet and heat shrink over that. Definitely overkill, but my truck sees 4' of water a few times a year.
