Two Questions

I have a 92 F150 4x4 auto E4OD.

1. How do I clear compute codes?
2. Where is the Inertia switch? The Haynes manual I have says it is on the firewall to the left of the brake pedal but I don't see it there. Am I just incompetent?

Clear computer codes by taking the negative battery cable off for about 10 minutes.
Don't have my books here at work but I am sure someone will answer number 2.

Your Haynes shows you how to read the codes with a paperclip. While it's blinking the codes, simply disconnect the jumper. This is the proper way to clear the codes.

The switch is there. It's a black plastic box about half the size of a pack of cigarettes. Reach up....way up...under the brake pedal and feel for a plastic box with a finger size hole at the top. That hole is the reset button.

in my 92 F150, the inertia switch is on the passenger side of the truck, behind a panel on the right hand side under the glove box.

Thanks GST97. Sure didn't know they had moved them!

Are you sure disconnecting the jumper won't destroy something? I was able to read the codes but couldn't figure out how to clear them.

And GTS97, you say behind a panel under the glove box. Are you talking about the passenger kick panel?
