We have a 2001 SE TD4 manual that has everything except cruise. I'm wondering if anyone else might have retrofitted the system to an FL1. I know the cruise ECU lives under the drivers seat (loom is there) and I would need the controls. And I know that I would have to source from the same model. But what I dont know is if the engine ECU needs to be told there is cruise attached or if it works it out off the cruise ECU's presence on the CAN Bus. Given it is drive by wire the cruise ECU will no doubt have to communicate with the engine ECU for speed and throttle opening information. I guess worst case I have to also swap the engine ECU too. Or perhaps aftermarket would be easier?

Any thoughts or insights?
