GO to any harware store, buy a basic set of multi purpose wire strippers, most have a crimping tooth; it doesn't meet all the way, it leaves a gap; on them, some with different sizes even. <$8.00 to do it right. You could also solder,but watch your heat, remember to heat the wire not the solder & use solder with self contained flux, to much heat and the connections become brittle - not goood in a car......
