Yeah all the SOHC 750's, as far as I know, had coils with molded-in plugs. You can cut open the casings with a dremel and replace the wires, but it's not a 5-minute thing. 70's Goldwings and later the DOHC 750's had coils with replaceable wires, you can use those if you match the impedance correctly.
