Mercury Cougar Electrical Problem?

Question:
My 1999 Mercury Cougar, with a 2.5 liter V6, continues to have electrical problems despite a recently installed new battery and alternator. The only way to crank the car is to jump it, and after I remove the cables, it stutters, the lights to dim and it shuts off. Also, a recently installed $150 brake light switch is no longer working. A friend indicates a computer/sensor problem here. Anyone have any ideas?, ......Help In GA !!
