To wire the mag to an outside coil, you have to disconnect the internal coil from the points, but leave the wire to the outside terminal connected. Hook up your outside coil with the + side to switched battery positive and the - side to the terminal on your mag (if it has a + ground, then reverse). If you have a mag with an external coil wire, you can run your secondary coil wire to the center tower on the "distributor cap" on the mag, and you're set! Just be sure your external coil is set up for the correct battery voltage (use a 12V coil for a 12v system or a 6V coil for 6V system). also be sure to observe the proper + or - ground.
