where is the emergency fuel shut-off switch on a 1985 ford thunderbird, (30th anniversery edition)

Hi tbirdman. I think what you are referring to is the impact shutoff switch which should be located in the trunk on top of the left-rear wheelwell. It's a good-sized button. If that doesn't get you there, your quickest solution is a call to your local Chevy service guy. Good luck!

if you don't find it there, look inside firewall straight back from where the e-brake is mounted.
