Ok cool. You verified you have a full 12v in crank at least and that's correct. Now you need to start back probing until you find power in the run circuit and see "where" that break is occurring. Kudos for that rig. That was smart.
ok, I just probed the yellow igniton wire terminal at the bulkhead with the key in run and nothing. Then i went to the inside of the car and checked it and still nothing.
