Buddy of my father in law is helping with engine wiring. Wants me to run a starter solenoid. He has been busy as of late and i am trying to wire it up and get this car started. On a 57 210 there is a wire bundle with black, dark green and purple wires in it. It is a ford solenoid so i have battery cable to one large stud and the other large stud has a lead to the starter. I also have the alternator wire hooked up to the battery stud. Thinking i should have a wire from the battery stud to the hei power wire. On one small stud on starter side i have a lead to ground. I have the purple wire to the small stud on battery side. Where do the black and green wires go? Anything else i need to know or hook up this solenoid to get things runnin?
