It's probably starting to rust out inside and is shorting. Your problem is not that uncommon. You can get them any where - all the "resto parts palces" carry them.

Do a search for "Ford truck fires" and you'll find some scary stuff. Ford used this same type of switch in their trucks from '92 into the beginning of this decade as a means of disengaging the cruise control when the driver stepped on the brakes. The switch was powered all the time and had a tendency to short out, overheat, and set the truck on fire - usually when it had been parked for hours. They work and they're OK as long as they're fused, but I personally replace them with a mechanical switch when I can. Corrosive brake fluid just doesn't really mix well with electrical parts. Just something to think about!

Use a 55 chevy switch. Mounted on the fire wall the the arm goes under the brake pedel. Works great. Also changed the rear lights complete sets. Just need to take out the pressure switch and plug. Thanks!!
