The way I was taught to join two wires with or without solder. It is
much stronger than the twist to a point method. See attached
illustration.

Thought the coils were a long shot.

I'm still not sure where the connection that failed was (connector contact
or the unknown connection at the end of the pigtail left by cutting the
connector off the Mazda harness) but I do like treating all connector
contacts with a corrosion inhibitor.  My favorite is Corrosion X.   I like
soldered connections for this reason too.  I'll do my own stress relief to
get it away from the potential stiff connection at the solder joint.  To
each his own though.

Greetings,

One way to use a solder connection and not have the liability of lack of
stress relief is to place an unshrunk heat shrink tubing (adhesive type) on
one of the wires to be joined. Take the two stripped wires and twist join
them (you will have the two wires twisted, coming to a point), and the heat
shrink tubing on one of the wires. Solder and trim the joint. Fold the
soldered connection against one of the wires, slip the heat shrink over the
wire with the soldered joint folded upon it and heat shrink it. If you are
really anal, before you fold the soldered joint onto the wire, you can add a
smaller heat shrink on the join itself and then add the final heatshrink
which insulates and strainrelieves your new solder joint.
