Question:

I need wiring for my 2020 Jeep Grand Cherokee, I already have a hitch and was using it for a bike rack. Now I need to tow a trailer and I know I need lights. The trailer doesn't have brakes, but I still need the lights. Which kit do I need for my Grand Cherokee? I checked and I don't have a tow package.

For your 2020 Jeep Grand Cherokee without the factory tow package I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118727. It's custom made for your Grand Cherokee and will give you all the required lights to safely tow a trailer, tail lights, turn signals and brake lights. It's a plug and play design, so there's no cutting or splicing into your Jeep's wiring. It installs in line with the tail light connectors to get the signals, and then a wire is ran to the battery to power it.

To keep the wiring from dragging on the ground and add a clean finished look I recommend using No-Drill Mount for Electrical Mounting Bracket # 18140 and Mounting Bracket 4-Pole Flat # 18144.

I attached a video of when I installed the wiring on a 2018 Jeep Grand Cherokee.
