The way I have this drawn up on schematic it goes back to a normally closed position. I would not cut into wire by ignition switch shuts off more than you need to shut off. Like your ecm and odometer all in one shot, and the all important ABS system and airbags. This is why I would not cut ignition off at switch with relay. Plus need odometer to figure mileage. I have installed also since 1995 and was Install manager at local ABC warehouse for about a year.

FYI: the way you describe you have the relay connected on normal open contacts. 87a is normal closed.
