Intermittent brake lights

[snowball]

HI all,

I'm having intermittent problems with my brake lights.

Tracked it down to the fuse box. it's lose and shaking it gets the lights on and off.

Anybody run into this before?

The fuse box is shaking?
there are two screws inside in opposite corners of the box under the dash., and one screw in the middle on the outside I believe. check the harnesses on the outside that they are plugged in completely.
check the screws that join the inside fuse assembly with the outside firewall where the front and rear harnesses attach. by the brake booster.
I think the real light harness goes under the truck. follow if from the rear of the truck forward and make sure everything is tight.
