OK, so I really need some help here... I'm hoping someone will reply to my post soon with some solid advise... I sketched a drawing with color showing my current wiring setup for my ignition system. From what I can decipher, my wiring is correct? I do have one question though on my current setup?? I noticed that the PURPLE wire running from the "S" position on the starter solenoid to the "SOL" position in the ignition switch is not showing up on any electrical diagrams I have come across? Is this proper for my setup or is it wrong? I appreciate any feedback you can give!!
