Here's everything from both the Factory manual and the Factory EVTM guide (electrical, vacuum troubleshooting guide) about the 87-91 Bronco ignition switch. If you're having ignition problems and suspect the ignition switch, lock cylinder or actuator rod then this is pretty much everything that Ford ever published about it. Hopefully this will help you solve any switch related issues that crop up and if nothing else it's good info to save & print for a rainy day
