Because of the reasons above, your best bet, without spending lots of
money on special crimping tools, a soldered joint is probably the most
reliable connection method for you. Stick with tinned wires and tinned
contacts, solder with 63/37 rosen based solder, don't apply too much
solder (it can wick up under the insulation), don't melt the
insulation, and clean the flux residue off with a spray cleaned. If you
do cover the ternination with heat shrink it's also a good idea to
cover the final termination with a product like Liquid Tape. A
connectoin made in this manner should last for a long time if not
exposed to too much moisture.

I hope this helped to answer your qusetion.

I use Ancor wire, Ancor terminals, and Ancor crimp tools. The
crimp tool for anything over 10 gauge wire is mallet (or hammer)
operated and it cost $20 or $30. My ratcheting crimper for smaller
wire cost about $50. These are the proper tools and the crimps are
excellent.
