Code 43 & ESC Problem (96 Z71)

Anyone have any info on how to get rid of a code 43? The book says that the power to the ECM is low, and also the ESC (electronic spark controller) might be at fault. Where is the ESC located on a 96 Z71? Also, what inputs feed the ESC? A wiring diagram would be awesome. One more thing, what is the PCY box (small white box by the computer) any help would be great.

you know what else would be awesome??? if you could get in the right forum.......if you fill your blinker fluid, the code might go away.
