My 1992 dodge D350 has no brake lights and the antilock light is on in the dash
Anyone had this problem. Anyone have the wiring diagram for these trucks.

Please help
Thanks

It usually helps when you tell us what steps you've done already.

There's a set of 91.5 diagrams in the sticky. (FAQ near top of forum) Probably close enough. The brake lamp circuit is quite convoluted with a fuse, brake switch, and multifunction switch (turn signal) all involved. It is, however, quite easy to trace and test with the diagrams.

and 99% of the time it's the factory disconnects at both rear frame rails, or the brake light switch itself.

But, since we have no idea what the OP has done already, we're just peeing in the wind, eh ?

FWIW, with any electrical problem the FIRST Thing I check is the fuse! CHECK it, for continuity, don't just look at it.
I'm a retired mechanic, and I can't count the number of vehicles that have been brought to me for electrical problems, that turned out to be nothing more than the fuse.

Not guaranteeing that's the problem, just that it's the place to start.
