Saw a post elsewhere (another forum) and trying to understand without going through 62 pages. 2021 Laramie, came from the factory with FCW. Other forum indicated that is the same camera needed for ACC. If you have the camera are other parts needed to enable ACC apart from the wheel mounted button (and subsequent enabling in firmware)? It seems the instructions were written for a model that didn't have any of the tech options; trying to determine if the other parts like the ABS module, center stack, etc. would be needed still or those work with a truck that has [lesser] tech packages.
Thanks!
