Auto Parts: 1995 Chevy Caprice, chevy caprice, water pump

Question
IM TRYING TO REPLACE THE ELECTRONIC SPARK CONTROL MODULE IN MY 1995 CHEVY CAPRICE, AND CAN'T SEEM TO FIND IT, ANY POINTERS IN WHERE IT'S LOCATED??

Answer
    I don't know, but it should be next to or near the distributor, which is located behind the water pump.  It is a white plastic thingy, kind of square.  It could be adjacent to the ECM, but usually not.  I don't have any thing here that would tell me, the engine setup used in these cars was only used for a few years and I've never worked on one.  Sorry.
