It is a 30 second job with an impact driver. The wiring is as described with a ballast resistor wired to externally resisted coil pos, and starter button side terminal also wired to coil pos.
Alternator wiring should be done 3 wire style. Alternator terminal 2 is wired to alternator Batt stud. Alternator terminal 1 is wired to an idiot light/charge indicator/12V bulb...... thru the bulb to ignition switch "ON".
Other considerations are: wiring for ammeter or volt meter and assume you know all the other things you need to do per our tip section.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
