For reliable electrical connections, use solder and shrink tube. Some kit manuals only advise using a crimping tool on their quick-attach connections, but experienced builders will tell you these fail sooner or later (usually during a pouring rainstorm, and far from home). A soldering iron with a trigger is the easiest to use. You will need a small vise or a stand with flexible "arms" to hold the wire and connector as you solder them together. Be sure to cut a short length of shrink tube first, and slide it on the wire before soldering. Then slide it back, over the fitting, and use a cigarette lighter or other heat source to seal the tube over the soldering. When cutting away insulation from wiring, be careful not to nick the wires themselves, as this can lead to bad connections or breakage. Ensure that any connections that slip-fit toge-ther have plenty of slack to keep them from pulling apart. Use electrical tape to seal them tightly, but realize that tape will loosen over time, particularly in engine compartments.
