A retrofit engine start/stop control system includes a programmable logic controller, an engine block temperature sensor to measure an external engine temperature, an ambient temperature sensor, an ignition circuit connector, a battery voltage sensor and an engine speed sensor. The programmable logic controller includes computer executable instructions to start the engine when at least one of an external engine block temperature, an ambient air temperature and a battery output voltage fall below a predefined threshold value for startup. A related method for retrofit engine start/stop idle control includes activating a programmable logic controller to control stop and start and idle control functions of an internal combustion engine; measuring an engine block temperature, ambient temperature, and battery system voltage; determining if all of the monitored values exceed corresponding predetermined threshold values for shutdown; and shutting down the engine if all of the monitored values exceed corresponding predetermined threshold values.
