Who's up for some Saturday night ignition switch fun???

Disconnect the connector at the column. Probe it and find out what is hot, it should be a large black "I think." That is your hot feeding TO the switch

Then hook it up and check the black and the orange while holding into "start." Both should still be hot in "start."

If that is the case, next stop is where the orange start wire goes through the bulkhead connector, and is a VERY likely suspect
