Yeah, for that "6 into 1" ground wire, I don't know of a crimp connector that will accomplish that. Solder seems to be necessary. Also, I'm sure the issue of vibration and solder joints is not a 99% failure rate. Chances are our connections will be just fine. I know I had to goop *a lot* of solder on there to get into all 6 wires. I feel like I could hit the joint with a hammer and it wouldn't break.
