I think I will be happy with my butt and soldered joints, since:
1. I will not be pushing any more than 12 volts, and have circuit breakers for amps over 30 for my a/c fan and one for my compressor as well.
2. The car is not driven daily and not much in the heat of summer. It is more for show and occasional jaunts with the car club.
Butt (pun intended) I will check the joints often if and when I get the car up and running. If the high voltage lines are not hot at the joints, will not worry about them.
Having said all that, I am very impressed with the knowledge expressed in the thread and will certainly benefit. Thanks much. Wish me luck.
