I have basically the same ones, but they are made by Klein. They are the cats ass.

All of them said that it's fine and normal practice to solder wire. The only time there is an issue is then you don't have the wire supported and it does a ton of bending right next to the solder joint. Basically - anything on your e30 will be fine. Any quality solder made for electronics is fine - solder till your heart is content. NASA requires RMA solder, and that's what all the wiring that is soldered on the space shuttle uses.
I work in the defense industry. We build high power/high voltage switchgear equipment for naval and commercial ships.
And the Navy and the Army, UNDER NO CIRCUMSTANCES, allow us to make connections/splices/solder anything. If a wire becomes damaged from mechanical wear, arc, etc, a new wire has to be ran point-to-point, no splices.
Even if it runs through 9 cabinets, through 15 different looms and is a single 90ft piece of wire, NO SPLICES are EVER allowed.
I have a hard time believing NASA would allow that on even more sensitive equipment.
If I'm wrong I'll glady eat a big bowl of "I told you motherfucker" stew, but based on my experience working with the Army/Navy, I have hard time believing that NASA has more lax standards.Need parts now? Need them cheap? steve@blunttech.com

Repair and new wire running are 2 different things. It makes sense that you aren't allowed to splice a cut wire back together, but running a new wire, soldering is fine at the ends.
This is how I understand the standards the two of you are talking about.'89 325i track sloot

Nope, no soldering on new wires as well.
Only crimped connections are used. And this is on $50k relay controllers and shit. No solder anywhere in SUPER expensive equipment.Need parts now? Need them cheap? steve@blunttech.com

For anything uninsulated and not the size of a whale's wanker,
Molex 63811-1000
I love these. What channellocks will do to insulated crimps, these are meant for precision. I build race harnesses with these mugs. Don't get them confused with the cheap crap at your local store. They make that perfect "B" shape, and are the perfect width for 90% of the crimps you will use on the car. They leave about 1mm of extra metal to flare out to give a proper crimp its "flexibility", and it passes the pull test.
These molex crimpers are bomb-ass. It makes crimps like factory. For about $50, I've used these to build harnesses on house water filtration machines, and of course, race cars.
For insulated connectors, the best is the Channellocks. The normal insulated connectors are hard to crimp correctly without breaking the insulation, and when you do crimp them correctly, the insulator falls off.
Of course we can get into die type mechanical/machine crimpers which are the real shit, but thats for another day.

and for solder...leave that on circuit boards and stuff.
