It just sounds like you have the +12v wire to a terminal that is not switched. Make sure you are on the spade terminal marked IGN. While it is common for an MSD to run on with feedback votage from a warning light, it is not possible for such small voltage to trigger an HEI since the only wire is the 12v wire. The MSD is hooked with 10ga wire to a constant 12v source and the activation voltage is miniscule which is why it runs on with feedback voltage.
