1990 E350 fuel safety switch location

It’s not behind the passenger side kick panel like online resources say… Don’t have the owners manual, & Ford online doesn’t have it available. Motor is 300 cu. in. 4.9L Inline 6. Just overhauled, haven’t been able to get it to fire… Any suggestions?

The Inertia Switch is located at the Left Hand Dash Panel above the brake pedal.
