All you need to do with that starter is to buy a 60-70's Ford fender mount relay. It must be grounded to operate the coil. Either large term to battery + and the remaining one to the starter. the small "S" terminal goes to the start signal at the key or starter push button, and the remaining small terminal "I" is your coil bypass. Just run a wire direct from there to the coil+ and that will give you the ballast bypass "hot voltage" to start
