The author shares their experience preparing a 1993 Volvo 940 Estate for the Carbage run 2025 Winter edition, a 6-day journey covering 6000km in less-than-ideal conditions. They retrofit modern electronic actuators, such as an electric power steering actuator from a 2020 Toyota Corolla and a Bosch iBooster for adaptive cruise control features. The surprising part is that the retrofitting process was smoother than expected, with the modern components fitting almost seamlessly into the older car. The author hints at future posts detailing wiring, custom ECU design, and openpilot porting. The unique aspect is the blend of old and new technology making the Volvo self-driving eligible for the event.
