Started with a harness with GM connectors, The colum has no wiring whatsoever. SO .... in typical street rod fashion I need to make this work. My turn signal switch is a dpdt center off switch(on off on) Brake light switch is pedal arm mounted as normal. But in wiring and making drawings I am always backfeeding the front turn signal bulbs with the brakes and turn signals on. I have tried relays and still have issues so I will check out the book and see, in the meantime I sure could use some help. All switches are under the dash for a cleaner better look, in essence this is a stock(free) harness with modifications.
