1. A start-stop retrofit kit, comprising:
- a start-stop module configured to monitor one or more parameters of a vehicle, configured to automatically stop an engine of the vehicle when the vehicle is idling during operation, and configured to automatically start the engine when the vehicle is not idling during operation; and
a wire harness configured to couple the start-stop module to a switch disposed between a starter motor and an ignition of the engine of the vehicle, wherein the switch is disposed in parallel with an existing connection between the ignition and the starter motor.

17. A method, comprising:
-
activating an engine of a vehicle based on driver input from an ignition interface; deactivating the activated engine during vehicle operation when the engine is determined to be idling or when a brake of the vehicle is applied, wherein the engine is deactivated using a circuit that is separate from the ignition interface; and reactivating the deactivated engine during vehicle operation when the brake of the vehicle is not applied, or when a transmission of the vehicle is not engaged, or when a parameter of a battery of the vehicle is beyond a threshold value, wherein the engine is reactivated using the circuit that is separate from the ignition interface. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A method of remanufacturing a vehicle comprising:
-
installing a start-stop module in the vehicle having an engine, wherein the start-stop module is configured to reduce an amount of time that the engine is idle during operation of the vehicle; communicatively coupling the start-stop module to an engine control unit of the vehicle via a wire harness; communicatively coupling the start-stop module to a brake system of the vehicle via the wire harness; communicatively coupling the start-stop module to a clutch system of the vehicle via the wire harness; coupling a switch to an ignition and starter motor of the vehicle as well as the start-stop module via the wire harness, wherein the switch is configured to start and stop the engine of the vehicle based on control signals from the start-stop module; and communicatively coupling the start-stop module to a battery sensor of the vehicle via the wire harness. - View Dependent Claims (25, 26, 27, 28, 29)
