If you want a quick answer, proper crimp splices are better than solder splices. Just get a nice ratcheting crimper with interchangeable dies and some un-insulated butt splices and you will have an awesome harness..

Good god, crimped shit, in a fucking airplane?
That has got to be one of the scariest thoughts I've ever had.
Crimped connectors will fail for metalurgical reasons, LONG before solder will. Crimped connectors will vibrate off, when solder will NOT. Crimped connectors can pull out, when solder can NOT.
If you are getting it hot enough to melt solder, you are getting it hot enough to soften crimp connectors. It's also hot enough that there will be no insulation, all your wires will be on FIRE, your engine bay PAINT will be on fire, everything will short. Your whole damn car could be on fire, before you need to worry about solder melting.
Solder has more surface area, and should make a better connection on those grounds, though I don't know how much resistance it has.... but it's used in precision electronics, it can't be THAT bad. Nevertheless, resistance, in some situations, MIGHT justify crimp connectors, I suppose. And maybe in some very specific locations, like right on a turbo, a crimp would make sense... is the insulation on that wire asbestos, or rubber? If rubber, solder is the better choice.
