By far the easiest thing to do would be to buy 2 new SPDT 
switches from your FLAPS and then go to a salvage yard and find 
a short MC harness from a 70-73 type 3. This harness is only 
about 1 meter long and runs from the MC up to just above the gas 
tank where you will find 3 in line connectors. You just install the 
new harness, matching wire colors.

The wiring itself is not hard, but I don't know how to describe it in 
words. Most manuals should show the late schematic.

I'm assuming that your car came with the brake warning system. 
Do you have the red light on the dash?

I should also mention that this whole warning system is pointless! 
The light doesn't come on until AFTER one circuit has failed and 
your foot has traveled 4" farther than normal and you have already 
started to panic.  8=0
