Dash brake light stays on
The.............................
I think he has "other problems"
The warning lamp should be dead with the key "off" so the E brake and warning lamp switches should be out of this equation
To the op, you need to figure out WHERE and WHY this thing is getting power
You may have a wiring cross (you might say short) that is causing a back-feed into this circuit
Find the warning lamp switch under the hood. Follow the brake lines down from the master cylinder. There will be a brass block with several brake lines and ONE wire. Unplug that wire
Go in as nm9 suggested, find the E brake switch on the E brake linkage and unhook that wire.
Now see if the problem still exists.........I bet it does
With the problem "showing" IE key "off" take a lamp or meter and hook to either the E brake wire or the warning switch wire to ground. See if you have power there
If you do you need to find where it's coming from
The way the warning lamp works is like this.................
Power comes from the key............up to one side of the lamp..........out of the lamp and branches off...........one wire goes to the E brake
One wire goes to the hydraulic brake warning switch
If either of these switches are activated, the lamp sees a ground
