Question:
I am looking at the redarc trail for my 23 Bronco. I tow not have the OE tow package and do have LED lights. I have installed the curt flat 4 unit previously. What do I need to do a complete install of the redarc controller? In the videos and pics I do not see how the vehicle connect to the to the controller for the brakes. Is there a rear harness to connect to the trailer?

Hey Marc, thanks for reaching out!
In order to get the Redarc Tow-Pro Trail Brake Controller w/ Custom Harness # RED54UR installed on your 2023 Ford Bronco you'll need to install the Universal Wiring Upgrade Kit # ETBC7. Some of the install might be a little touch and go because some Broncos come with factory wiring for the brake controller and others don't, but if you follow along with the linked 2024 Bronco install video you'll be able to get it all figured out.
The wiring kit comes with everything you need in addition to your Curt 4-Way to get the brake controller installed.
Let me know if you have any other questions!
