Now on to soldering ! Since we agree that solder is worth its weight in gold... when you get those matching wires.... take some flint sand paper and spread them into a fan shape and fold the little piece of sandpaper and pull it across the copper wires a couple of times.. they should be really pretty....you have done this to both matching ends that you are going to put together..... BUT WAIT... YOU MISSED A STEP.... first put an appropriate size piece of shrink tubing...on one of the wires up out of the way..., both in hole diameter and length.. remember it will shrink and that you have to be able to get it up over the wires you are going to twist together end to end... just integrate the fans and twist....then if you are out under the car,,, a really nice touch is the little piece of flat solder already cut which you can just wrap around the joint and use a match to melt into it... or you can use a soldering gun... some are even 12 volt... after you melt the solder and it has cooled... and it is always important to keep the wires stationary until the solder has fully cooled... then you pull the tube of shrink tubing down and center it on the joint.. then you use another match... or really hot air gun with the curled adapter on the end... to shrink the tubeing onto the wire... you will not have to worry about corrosion at this place for many years, if ever. I said flint sand paper so you don't use wetordry,,,silicon carbide because it leaves particles that corrode stuff,,, this is why you don't sand distributor points with it.
