I am in agreement with Gene and the the rest of you guys here. Repair is far easier and economical. Yes, being the ultra conservative person that I am with this sort of stuff, soldering the connections for extra good measure is what I do. Having said that, there is one hell of a lot of military equipment out there that utilize crimp type connections. When I re-wired RamJet with a custom wire harness for my Accel Gen VII installation. I used the process described in the following link adding standard shrink fit tubing over the top of the splice.
Tyco wire to wire splice
For my money you can take that black plastic corrugated cable tubing that most aftermarket automotive cable harness manufactures use and pitch it.
I did the custom wire harness in the 70 Corvette using quality Nylon (plastic) braided sleeving and shrink tubing. That made for a much cleaner and better harness than using the lousy accordion plastic tubing.

Gene, Yes I know you could use a "Western Union splice" with solder and shrink tubing, and do it cheaper, but for my money and my car, I think this is worth the effort.
