Review on 🚗 Jeep Grand Cherokee Compatible 4-Way Flat T-Connector Harness by Tekonsha T-One by Sammie Rodriguez

Installed on my 2019 Jeep Grand Cherokee Altitude. All taillights work and the module has power, but the 4-pin connector does not work. Update: I ordered a new one and it worked perfectly. I think the previous one had a bad module. You don't have to go to Jeep to activate anything for them to work. The hardest part was stretching the power cable to the battery. I ran under the right rear seat straight to the battery vise which connected to a connector under the hood as shown in the video.
