With the key "On", the E-brake switch connection should have power.

The circuit is completed when the switch makes a ground connection.

If you unplug the switch at the e-brake (or the proportioning valve) and ground it... the light should come on.

If the wires to those two switches aren't getting power... the problem is probably in the connection to the cluster circuit panel, corrosion at the lamp socket contacts or a broken wire.

Good Luck!
