Been keeping an eye in all this, Just a short for y'all that are interested;
2019+ Ram 1500 with ACC and LaneSense
Owners of Ram 1500's interested in making Openpilot work with their trucks would need a Comma two (c2) and Dev Harness, outfitted with connectors as found in this document:
https://1drv.ms/b/s!AhlEjIwibjKfiZojQ_EU934HfcvMHA?e=mOVWBh. Discord user Tunder has a working fork for Ram 1500's. It is in active development, and does NOT conform to comma's safety standards. It has working lateral control as of March 28, 2021. Ram 1500 owners are encouraged to contribute to the development and upstreaming of the Ram port to comma's openpilot repo as a community supported vehicle. The software can be found here:
https://github.com/Tundergit/waifupilot.git, branch 082-testing. Use of this fork is entirely at your own risk, and nobody but you is responsible for anything that happens as a result of the use of any documents or software linked on this page.
Ram 2500 and 3500's equipped with Active LaneSense may also be eligible candidates, late models have an electric assist motor that may be actuable.
Ram models with the radar behind the mirror may be openpilot longitudinal support eligble, and is something that will be investigated in the future.
