Car still runs with key off ..have I wired this right?

And what crackedback posted is important..........there might be something wrong with the MSD. Those turn on/ off like a relay, that is the main power for the MSD box comes direct from the battery, the "big red" but the on/off command/ trigger comes from the small red. So as he said, something might be "bleeding" (bad ignition switch?) or a MSD problem might be causing it to remain live regardless of the trigger
