I want to fit Cruise to a 2014 Relay with the Ford 2.2 engine (I know Fiat don't fit this engine). The reports I have read about earlier vans say that the wiring is missing so forget it, but I have the 6 pin plug for the cruise stalk next to the indicators. My 6 pin plug only has 2 wires (1 & 6) and they are yellow and red respectively, I believe these to be the CAN bus wires.

Given that the Citroen is wired for cruise can I add the stalk and enable it? Thanks.

I retro fitted CC on my 2011 Ducato with the same 2.2 engine. I had the connector on my steering column, and the switches on my brake and clutch pedals.
It was a 45 minute job, and works a treat. You will need to reset the learnt functions on the ECU, or disconnect the battery while fitting, so the ECU relearn CC is fitted.
