The EEC module is the Evaporative Emission Control (also sometimes called the Electronic Engine Control). It does a number of things, but its main purpose is to adjust the air/fuel mixture to maximize fuel efficiency.
EEC stands for Electronic Engine Controls. The EEC Relay provides power to the computer.
A 1994 Mercury Cougar is OBD I , EEC - IV ( there should be an EEC TEST connection in the engine compartment )
Voltage regulator is located behind the battery in the inner left (driver's side) panel, in the front part. You must remove the battery in order to reach the regulator. Use a quality replacement part or your eec computer may go toast. Voltage should read aprox. 12V with engine off, and about 15V with engine running. Good luck fella.
