First time towing something over 1500 lbs and I now need to hook up an electric break. I own a 2007 Jeep Commander(4.7L V8) with built in tow package, tow rating around 6000 LBS, I’ll be towing around 2500 LBS. I have a 7 point connector port on the back and the flap says lights and brakes on it, so I know the wiring is there. I couldn’t find much information online about the brake controller, one site mentioned looking for a green wire in the driver side floor. I pulled the carpet up, but they have everyone wrapped up so tight in shielding so I couldn’t see anything without cutting into it. So in looking in the fuse compartment area under the steering wheel, I see a green wire coming up mixed in with a bunch of red wiring and there is also a green wire feeding into the onboard diagnostics port. The question is what controller do I need? Is there a plug and play option or does it need manual wiring? I’ve attached a pic for reference. Any help or suggestions are greatly appreciated!
