The single module engine controller is located on the center of the firewall above the engine. You got it.

Voltage regulator is internal to the PCM. For testing see Charging System/Testing and Inspection, here is the location of the PCM. The engine controller is located at the center of the firewall, above the engine. Check out the images (below). Let us know if you need anything else.
