Cruise control for 2017 CT
Dear Club!
I need help to add cruise control to a lexus CT. I purchased the maneuver and the cap on the internet, reinforcing many other threads on the forums, and supposedly only needed to do these two things. The so-called PLUG&PLAY. Unfortunately there was PLUG and there is no PLAY. The maneuver buttons do not work, the car does not respond. My question is what can I still do on my own? Have I been unlucky and the manoeuvre that came may be defective, or in the 2017 post-lift (prod 10.2023) there are no cables located behind the plug? Is it necessary to add some more fuse?
Thank you for your help!

My guess is that you'd need to convince a dealer to reflash the ECU with a build that supports cruise control functionality. That, or there may be a dealer-only parameter to enable cruise that has to be toggled. I ran into this when I added factory cruise to a 2010 Mazda that I used to own. Dealer had to turn the function on for it to work.
