Ed: The cap for the reservoir for the brake cylinder has a very obvious electrical plug, orange in color, on the top of it. See the Brakes page at www.specialtauto.com <http://www.specialtauto.com/> for some photos. You would have immediately noticed that the wires were not plugged in if you saw the right thing. Either you found the clutch fluid reservoir instead, which does have a smaller plastic knob, or someone switched out the cap with a generic one and it has no sensor. Make sure you found the master brake cylinder, and that it is shaped like the one in the photos. If you have the wrong cap you will need to talk to the vendors about getting a new one. If you disconnect the wires you can either find them from below fixing around, or maybe from above if you remove the fuel pump access plate under the spare. Once you have a proper cap with a float sensor and the wires connected, you can manually move the float up and down to check proper operation of the embedded switch.

Hand brake switch is operating correctly. Disconnected switch and checked with ohm meter in on and off positions. Grounding wire made no difference either. On to the master brake cyl. Opening the plug I found no wires you referred to, only a small plastic thumb screw top on the reservoir which was full. What to check next? Does the access panel to the master cyl need to be removed to check further? I begin to see why simple does not fit the DeLorean vocabulary.
