Abstract: The disclosure relates to simplifying the integration of a peripheral with a vehicle. The complexity of modern vehicle electronics means that integration of a peripheral with a vehicle requires a reconfiguration of the vehicle electronics in order for the resultant upfitted vehicle to function as desired by the user. This restricts the set of users and enterprises which are able to successfully integrate a new peripheral with a vehicle. To make the task more approachable, a software application is described which presents a user with a graphical user interface enabling them to specify, at a high-level, rules of behavior for the upfitted vehicle. From the user's inputs via the graphical user interface, the application creates configuration data to be applied to the vehicle electronics in order to produce the desired behavior in the upfitted vehicle.
