Where exactly are these rear cup holders?
And can someone expand on the acronyms?

The engine control module (ECM) is a type of electronic control unit that determines the amount of fuel, ignition timing and other parameters an internal combustion engine needs to keep running. It does this by reading values from multidimensional performance maps (so called LUTs), using input values (e.g. engine speed) calculated from signals coming from sensor devices monitoring the engine.
The transmission control module or TCM is a device that controls modern electronic automatic transmissions. A TCM generally uses sensors from the vehicle as well as data provided by the Engine Control Module to calculate how and when to change gears in the vehicle for optimum performance, fuel economy and shift quality.
A body control module is a computer component in an automobile that checks, regulates and operates electronic devices throughout the car. When electric devices first began being used in cars and trucks, each device had a separate electric component to govern it. There was a module for the air conditioning, a module for the interior lighting, a module for the door locks and so forth. A body control module gathers all these separate modules under one system so that they function together instead of separately, a format easier to both manufacture and troubleshoot.
While there are many different types of body control modules, they are generally alike, connecting sensors, switches and automatic reactions together in one computer system. These components are divided into inputs, such as sensor data about heat or speed, and outputs, or ways in which the body control module computer responds to control the vehicle's electronic functions. Inputs and outputs are further divided into analog and digital types of information, analog signals being used with modules that may change continuously (such as oil pressure) and digital signals being used for modules that can simply be on or off (like the headlights or the oil indication light).
This control system can monitor numerous categories and types of data during operation of the vehicle. The control system can receive signals from one or more velocity sensors to monitor vehicle speed, from one or more lateral acceleration sensors to monitor vehicle stability, from diagnostic sensors to monitor conditions such as temperature, pressure, and engine revolutions per minute. Also, the control system can monitor serial/parallel data as well as analog/digitalsignals
The control system can also execute several different types of commands. For example, the control system can receive input from the driver and control the functions of an entertainment system of the vehicle. Also, the control system receive signals from vehicle sensors and execute commands. For example, the controller can receive a signal from a windshield rain sensor corresponding to rain and control the windshield wipers to engage.
