Well, as some of you may know, I recently removed my front fender. Driver's side to be exact. Anyway, I had to unplug a device, and I couldn't help but notice that the truck wouldn't start with it unplugged!
Anyway, it's a little metal object gray in color that resembles a heat sink in a computer... that's as close as I can get to explaining it. It has a wire harness coming out of it, and that's what I had to plug in to make it start again.
On the driver's side under the hood hinge mechanism you have an aluminum finned module. We used to call it the ignition module in older electronic ignitions and it used to be a heat sink and go bad regularly on some makes.
Tex is right-on with his assessment (like he really needs someone to back him up or something ). That gig bolted to the fender is the notorious Thick Film Ignition (TFI) module. For years the grey plastic module itself was bolted to the distributor right below the cap, but they were quite susceptible to failure due to overheating, which even inspired a class-action lawsuit a few years ago. Ford's better idea was to mount it as far away from the heat source as practical, so it ended up on the fender of the '92-up trucks.
