Question:
Need a controller for 21 Jeep Grand Cherokee w/factory tow. Want the Redarc Liberty. This article links to the controller and necessary pigtail, but also mentions a 3045-S adaptor that I can find nowhere on your site. https://www.etrailer.com/question-561541.html Assuming the article is still accurate, can you advise on the missing item?

Hey Will, we have what you need to install the Redarc Tow Pro Liberty part # RED52VR in your 2021 Jeep Grand Cherokee but you will need to use the Curt harness part # C51446 instead as the Tekonsha one you mentioned is unavailable at this time. You will need to cut off the end of the harness and hardwire it color for color to the Redarc.
