Brake warning light on dash

Very good if your warning switch is still working. Most get rusted in place. I think the emergency brake handle switch triggers the same lamp. Both short to ground to light it, so if either wire shorts to ground that would as well. For those w/ later Mopars (my 1996) or if you install a later MC (my A's), the reservoir low-level sensor similarly shorts to ground to light the same lamp.
