The installation is clean and reversible.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo cruise control and engine brake work from the factory steering wheel?\u003c\/strong\u003e\u003cbr\u003eDepends on the mode you choose. In \u003cstrong\u003eMode 1\u003c\/strong\u003e (standard, included) they connect to independent switches mounted near the driver. In \u003cstrong\u003eMode 2\u003c\/strong\u003e (with the CTS-integrated module) the Cascadia's factory steering wheel buttons keep working 100%.

Choose the \u003cstrong\u003e14.0L DDEC V\u003c\/strong\u003e configuration in the selector. For the Cascadia 2009-2017 it is even simpler: the DDEC V speaks native J1939, needs no additional module, and the steering wheel controls work directly.
