Re: LED strip for turn signals
If it's a high vibration area where the wires would be subject to moving quite a bit and you can get a good solid crimp. Do that.
Soldering locks the wires down and forces the vibration and movement to be taken up by the strands right at it's edge. When you crimp, the individual strands can still move just a fraction back and forth and absorb this stress better. On everything.. unless it is a low voltage connection... try to crimp.
I always insisted that techs carry a ratcheting style crimper, that way it helped ensure the crimp was full press since they don't release till you go through the whole cycle.
I agree with you for the most part for any one that is in the bigger the blob better the job type of soldering.
If have to know what your doing when soldering. Thanks to the Navy I'm in the group that has way more soldering training and experiance than I will ever need again now that I'm retired from that part of my life. I just assume anyone working with wiring or electronics knows how to properly solder, possibly a bad assumption on my part.
I also like the ratcheting crimpers for small pins and happen to have one in my toolbox, the problem with more than one wire in the pin and the crimper is it still crimps like theres only one wire inside the pin and can actually punch through the pin if it's not adjustable for how far you want it to crimp.
Now, back when I was younger I remember just twisting wires together and slappin some electrical tap on it... worked like a charm for the time I had the item. Heck even slipping a wire under the fuse works.
I think we can all agree, many ways to get the job done.
