It's cool man. I respect your opinion. And to be honest, there's no way for me to argue that twisting the wires together is going to be as secure as soldering the wires.
If someone said they twisted/taped their head unit wiring harness, then I'd look at it the same way you're looking at this. I'd say that's a bad idea. Lots of wires - lots of small, thin wires - with the potential to come loose, and a PITA to pull the deck and find which one is the problem. For things like that, and just about all other wiring, I solder. But for this we're dealing with only 2 heavier gauge wires.
I guess it's a matter of opinion which description of this is going to be easiest to understand for someone. My whole point was simply to show, with one picture, how you have to wire it. Everyone is going to draw their own conclusion on how they want to secure the wires, and that's fine. But first you have to know how to run your wire, and that's really all I was trying to show. And again, in my original post, I said you can solder the wires.
I'm not lying when I said this has worked flawlessly for me. If at any point, the connections had ever come loose on me, there's no way I would have even suggested doing it like that.
I was just showing how to run the wire from point A to B without charts and diagrams and crap.
