2nd Gen Non-Engine/Transmission no brake lights

[SamBrown]

so all of a sudden i noticed no brake lights on the box and the light on the cab? bulbs are good, but i hooked up my meter and have no power at the plug? fuses all good, anyone know where i should start troubleshooting?

What yr. truck ?
What do you mean by box ? A trailer brake box ?
Check the brake sw. at peddle .

Check under the hood on the drivers side ... . Fuse box for brake lights also there is a fuse labeled trailer that only controls the trailer lights... .

Good luck
