Re: Brake light on the dash- help needed

What the switch does is ground the wire that plugs into it and this provides a path to ground for the light. If you disconnect the wire the light should go off unless the wire is shorted to ground in another spot. You could check this easily with a meter.

here is a picture of the valve and the wire that we are talking about.

I have read that a really hard stomp on the brakes will reset the bias valve too.

I forgot to say. to the forum.
