Un-hacking ignition wiring

It was common to bypass that plug for the ammeter/volt meter hack, as well as changing to electronic ignition with an electronic regulator. Easiest way is to get yourself a roll of 18g stranded and start running replacement wires per the electrical schematic. Take your time and get a crimper and lug kit from HF or amazon. Solder everything you can, the bullet connectors only go so far. also get some multi color electrical tape so you can label the same colored 18g wire at the junctions so your schematic will make sense to you 5 years from now. Being a telephone man makes this the easiest method for me as I run, repair and trace wires all day out in the field.
